:*SW1 results are coming to you this evening. A couple of specific points:
+
===Hibbing, Chapter 4: Drunk Flies and Salad Greens (89-96)===
::*The general level of writing was pretty good.  You should not impose a grade distribution on the numbers.  They mostly reflect an assessment relative to the rubric.  13/14s are great, 12 is pretty good, 11 ok, 9s and 10s - great opportunity for improvement.  ''Seriously, it would not be difficult to move those up.'' This is not a curve.
 
::*No grades were determined by these results.  They are probably accurate to +/-1 point.
 
::*This is not really the end of the assignment, but the beginning of a great opportunity to work on your writing. You can start that process by looking at the scores and reading several peers' essays.  Consider visiting the office (zoom or in person) to discuss your writing. 
 
  
:*We are ready to start Back Evaluations.  This gives you an opportunity to reward peer commentators who did a particularly good job with their comments.  Please focus on comments, not scores.  '''You must complete back evaluations to receive credit for the assignment.'''
+
:*From Fall2020 Philosophy of food, Food News!:
::*Stage 4: Back-evaluation: After you receive your peer comments and my evaluation, take a few minutes to fill out this quick "back evaluation" rating form: [5]. Fill out the form for each reviewer, but not Alfino. You must do the back evaluation to receive credit for the whole assignment. Failing to give back-evaluations unfairly affects other classmates.

:*Note this "conceptual point": Point about fruit flies: taste for glycerol has biological basis, manipulable, yet we'd say the fly "likes" beer. POINT: Variation in human preferences yet also biologically instantiated.  They are still your preferences even if (especially if?) biologically instantiated.  Focus on this chapter: taste/prefs diffs of conservatives/liberals, their basis, connection to politicsLater, cars, stocks, etc.
'''
 
::*claims that in the 80s we started describing food in terms of nutrients.   
 
  
::* credits William Prout with discovery of centrality of protein, fat, and carbs.  Liebig credited also.  Also discovers role of nitrogen phosphorus, and potassium in growing plantsClaims to have solved problem of nutrition.  [There was a big question among chemists about what it is in food that keeps us alive.  Recall this is mid-19th. Chemistry came late to the scientific revolution in the 17th and 18th centuries.]
+
:*Note also that they are acknowledging great variation in preferencesNot reductive.
  
::*”Extractum Carnis” — big business for Liebigearly example of meat protein ideology. Didn’t work as baby formula.  
+
:*Obama's arugula faux pasHunch.com studies (note problems): supports stereotype. 92: preferences not random in a population IPhone users and Rice Krisppie eaters.  
  
::*Alludes to the discovery of the causes of “scurvy” on shipsReluctance of outfitters to give sailors fresh citrus.   
+
:*Hibbing et al research 93-4: favorite meal v. new dishexpanded preference research to: new experiences, humour, fiction, art, prefs in poetry, living spaces.   
  
::*discovery of vitamins 1912. Casimir Funk.  Note the “vitalism” in the name.
+
:*Market research in politics: mentions RNC research: Conservatives favor Porsches vs. VolvosConservatives more brand loyalFavor different investments.
:::*addressed scurvy and “berberi” B1 (Thiamine) deficiency.
 
:::*[Digression on ThiaminePart of a coenzyme that facilitates the energy production cycle ATP in cells“I can’t, I can’t”. Related to the onset of machines for producing polished rice.]
 
  
:*First modern conflict between US dietary advice and US food industry.
+
===Hibbing, Chapter 5: Do You See What I See?===
::*22:  1977 McGovern Committee:  first Diet Goals for the US. 
 
  
::*Lipid hypothesis: claim that high levels of heart disease in the US were result of dietary fat consumption, especially from meat and dairy. Not great evidence base at this time. 
+
:*Attention Studies research on Political difference:
  
:*Committee rec. reducing fat intakeBacklash.  To avoid targeting a particular food industry, the committee started to use broader catergories of foods and nutritional markers to identify dietary goals.  McGovern loses reelection, with help from beef lobby.
+
:*Rorschach testsseem to trigger different attentional and other biases.   
::*Instead of “eat less meat and dairy” - “choose meat, dairy, and fish with less saturated fat.” 
 
::*Nutritionism as an ideology: Foods seen as delivery systems for nutrientsSome scientists like T. Colin Campbell objected, claiming that food and diet is still a legit level to see relationships.  '''Heart disease might not only be about fat intake, but also lack of plant based foods.''' [Mention ''The China Study'' — some big criticisms, but later research on fats in context of plant based diet aligns with Campbell’s research.]
 
  
:*Even when plants were understood as beneficial, they were described in terms of anti-oxidants, vitamin C, and carotenes.  
+
:*Claim in this chapter: Differences in political temperament are tied to differences in a variety of perception and procession patterns prompted by stimuli.  Liberals and conservatives see the world differently.
  
:*Nutritionism - the assumption that the right level to think about food nutrition is the biochemical level.  [Not so much wrong as limited. There are wholistic effects from diets that involve complexity best captured by “diet” and “food types” (e.g. colors of vegetables predict benefits).]
+
:*The Eyes Have it
  
===More Fat Facts===
+
::*'''Eye movement research - gaze cuing''': gaze cuing test reveal sensitivity to social cues for everyone.  Everyone is influenced by the gaze direction on the face. But these are averages.  lots of variation. 
  
:*Our treatment of the dangers of saturated fat is standard nutrition science, but a more sophisticated understanding of fat has emergedHere’s the update:
+
::*research question: Are liberals more susceptible to gaze cuing than conservatives?  Yes. liberals slow down under miscuing, but not conservatives.  liberals are more sensitive to social context, conservatives to rules121: not necessarily one better than the other.  But, interestingly (122) conservatives and liberals prefer their own attentional biases (at least weakly)!  (Speculate here.)
  
:*1970s: We thought saturated fat was a sufficient cause of heart disease.  American Heart Association cashed in on lipidphobia and still does.  Food companies pay a lot for their seal of approval. 
+
:*Fitting Round Pigs into Square Holes 122
  
:*Later studies (Lancet 2017) looked at 135,000 people in 18 countries and found no correlation between fats, fat intake and risk of cardiovascular disease or cardiovascular disease mortalityShocking!  [https://www.thelancet.com/article/S0140-6736(17)32252-3/fulltext Lancet study]High carb, high fat diets do have risks.
+
::*'''Categorization as Cognitive Temperament''': tests allow us to see variations in cognitive temperamenthard categorizers vs. soft. Conservatives / liberals124: conservatives more likely to lock onto a task and complete it in a fashion that is both definitive and consistent with instructions.
  
:*More recent studies support Campbell’s hypothesis that plant based diets have a protective effect against some fat consumption. 
+
:*Our Thoughts are Our Own - Or Are they?
  
:*[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893503/ Plant-Based Diets in the Reduction of Body Fat: Physiological Effects and Biochemical Insights]More popular source: [https://www.usnews.com/news/health-news/articles/2021-06-09/plant-based-or-low-fat-diet-which-is-better-for-your-heart 'Plant-Based' or Low-Fat Diet: Which Is Better for Your Heart?]
+
::*'''Cognitive Processing of + and - content'''. Italian researcher Luciana Carraro, why do some people tend to pay attention to negative words over positive words?  Used a '''Stroop Task''' measuring delay in reporting font color of negative wordsStrong correlation with political orientation. "'''conservatives have a strong vigilence toward negative stimuli'''."  Wasn't so much the valuation placed on negative words, but that negative stimuli triggered more attentional resources.
  
===Moss, Ch. 8, "Liquid Gold"===
+
::*[We can also associate this result with other research suggesting conservatives have better awareness of "threat detection".  Not surprisingly, our military skews conservative, while the academy skews liberal — people drawn to research may be motivated by neophilia.]
  
:*Wallace and Grommet on cheese: [https://www.youtube.com/watch?v=C7rzSslub6U]
+
::*Same researchers did a '''Dot Probe Test''' (measuring speed in identifying a gray dot on a positive or negative image.  Speed increases with attentional disposition toward the stimuli). Liberals a bit quicker with positive images, conservatives with negative.
  
:*Stories told in this chapter: Dean Southworth and Cheese Whiz; James Lewis Kraft, cheese entrepreneur!; story of cheese in the US food economy; Kraft marketing of Philadelphia cream cheese and Paula Dean story; closing research on visible/invisible fatsThere is no upper bliss point for fat!
+
::*Hibbing et. al. wanted to replicate the Italian research.  Used a '''Flanker Task.'''  (measuring speed in reporting a feature of an image when flanked by two images congruent or incongruent to the main image. Assumption is that the less you are slowed down by incongruence, the more attentional resources you had for the image.) Replicated typical results: we are all faster with angry faces, for example.  Conservative less impacted by the angry faces.  Both groups reacted the same to happy faces.
  
:*'''Cheez Whiz'''
+
:*What Are You Looking At? 129
  
::*Cheez Whiz; altered from original, but never a gourmet experiencePretty much no cheese in it now.   
+
::*'''Eye tracking attentional studies - '''dwell time'''.  Their research measured "dwell time" - time spent looking at an image. In a study, subjects are shown a group of imagesGeneral bias toward negative images. Theorized as having survival valueConservatives spend a lot more time on negative images and quick to fix on negative imagesSome weak evidence that liberals focus more on positive images, but sig. results concerned differentials.   
:::*2 Tbs have 1/3 maximum saturated fat and 1/3 of max sodium allowance.   
 
:::*Am cheese consumption:  33pounds/year; 50 gallons of soda.  [https://www.statista.com/statistics/183785/per-capita-consumption-of-cheese-in-the-us-since-2000/ Now 40 pounds, but good news, it’s hitting a plateau!]
 
:::*traditional consumption of cheese (mention Cesare & Ornella)
 
  
:*'''Kraft origins story'''
+
:*Perception is Reality -- But is it real? 133
  
::*1912, James Lewis Kraft invented canned cheeseused in field rations1928: Velveeta, high sodium as by product of industrial process.   
+
::*Since liberals and conservatives value positive and negative images in the same way, you might conclude that they see the same world but pay attention to parts of it with different degrees of interest or attentionBut Hibbing et. al. are not so sureIn a study, they asked libs and cons to evaluate pos/negly their view of the status quo on six policy dimensions (134)They seem to assess the reality differently, '''they see different policies at work in the same society''', not just attending more to some stimuli'''Political difference might not be difference in preference, but in perception.'''
::*Eventually Kraft uses an emulsifier, Sodium phosphate, but that increased sodium and reduced cheese flavor.   
 
::*point is that industrial cheese can be made in a few days.  “Milk in, cheese out” fresh cheeses are quick, but real solid cheese can take 18 months or more to mature. (Is that a real value or just an old way of doing something?).  note 167. 
 
  
:*'''Cheese in US food economy'''
+
::*They also did some research on ranking degree of negativity of images and, unlike the Italian research, conservatives did rank negative images more negatively. In another study (135-6), researchers (Vigil) found that conservatives ranked faces as more dominant and threatening than liberals.  [Interesting that in both the 1918 pandemic and today's, conservatives resisted mask wearingNice coincidence with today's bizarre mask politics story.]
::*anti-fat campaign of 80s led to overproduction of milkfat ("Cows can't make skim milk" - maybe a clue that something's backwards), gov't subsidized milk and cheese; huge warehouses of cheese (1.9 billion pounds at a cost to taxpayers of 44billion a year) ;  Reagan admin stopped this, but also raised funds from the industry for new marketing efforts to promote milk consumption. 
 
::*1983 Dairy and Tobacco Adjustment Act.  [1993 Got Milk? Ad campaign for California Milk Processors Board]
 
::*Note the gastronomy segement 171-172 - ex Kraft cheese expert Broockmann.   
 
::*Update.  Only 1.4 billion pounds in storage!  [https://fee.org/articles/why-does-the-federal-government-have-14-billion-pounds-of-american-cheese-stockpiled/]
 
  
:*'''Philadelphia Cream Cheese'''
+
:*You're full of Beans
::*"Sliced" didn't work.  spreading is part of the fun, but also suppresses serving size information. p. 174: '''no bliss point for fat'''. 
 
::*Kraft Mac & Cheese. Extended product line with added cheese varieties.  Up to 15 grams of saturated fat.  Then you are meant to add beef!
 
::*Nutritional profile might not look bad at first glance [http://nutritiondata.self.com/facts/meals-entrees-and-sidedishes/5964/2], but check out this comparison [http://www.motherjones.com/blue-marble/2013/03/kraft-mac-cheese-dye-annies-cheez]
 
::*Stuffing cheese into pizzas. 
 
::*Early social media marketing effort using Food network star Paula Dean, targeted to women — “Real Women” (amazing: Mac and cheese, wrapping in bacon and deep fried!) and social media to generate interest. Creating industry based food culture.  5% boost in sales. Sadly, Paula Dean get diabetes and switches her sponsorship to a drug company.
 
  
:*'''2008 Dutch research on visible / invisible fats'''
+
::*'''Cognitive style in exploration - '''BeanFest'''''' -- a research game in which test subjects try to earn points by deciding whether to accept or reject a bean with an unknown point value.  Based on personality, some subjects are more exploratory (accept more beans and get more information), while others are conservativePolitical orientation also predicts strategyShook and Fazio see the result as indicative of differences in data acquisition strategies and learning stylesInteresting follow-up analysis based on giving test subjects a "final exam" on the bean values. Similar scores, but different patterns of classification. 
::*visible / invisible fats and satiety, perception of fatresults: everyone underestimated fat content, visible fat group full faster, about 10% more.   
 
::*Personal advice: buy whole fats and eat them sparingly and mindfullyCompare satiety with Costco sized skim-fat products.
 
  
::*Puzzle: many cultures eat much more cheese than Americans.  French 53, Italy 44, Germans 46, yet do not suffer dietary disease from it as we do[Now we have some answers to this, though there is skepticism about the French!]
+
::*139: good summary paragraph: "New bean? What the hell, say the liberals, let's give it a whirl"  Roughly equal scores on the game and exam.

  • Neuropolitics as focus of research [2]
  • Note this "conceptual point": Point about fruit flies: taste for glycerol has biological basis, manipulable, yet we'd say the fly "likes" beer. POINT: Variation in human preferences yet also biologically instantiated. They are still your preferences even if (especially if?) biologically instantiated. Focus on this chapter: taste/prefs diffs of conservatives/liberals, their basis, connection to politics. Later, cars, stocks, etc.

  • Market research in politics: mentions RNC research: Conservatives favor Porsches vs. Volvos. Conservatives more brand loyal. Favor different investments.

Hibbing, Chapter 5: Do You See What I See?

  • Attention Studies research on Political difference:
  • Rorschach tests. seem to trigger different attentional and other biases.
  • Claim in this chapter: Differences in political temperament are tied to differences in a variety of perception and procession patterns prompted by stimuli. Liberals and conservatives see the world differently.
  • The Eyes Have it
  • Eye movement research - gaze cuing: gaze cuing test reveal sensitivity to social cues for everyone. Everyone is influenced by the gaze direction on the face. But these are averages. lots of variation.
  • research question: Are liberals more susceptible to gaze cuing than conservatives? Yes. liberals slow down under miscuing, but not conservatives. liberals are more sensitive to social context, conservatives to rules. 121: not necessarily one better than the other.

  • Our Thoughts are Our Own - Or Are they?
  • Cognitive Processing of + and - content. Italian researcher Luciana Carraro, why do some people tend to pay attention to negative words over positive words? Used a Stroop Task measuring delay in reporting font color of negative words. Strong correlation with political orientation. "conservatives have a strong vigilence toward negative stimuli." Wasn't so much the valuation placed on negative words, but that negative stimuli triggered more attentional resources.
  • [We can also associate this result with other research suggesting conservatives have better awareness of "threat detection". Not surprisingly, our military skews conservative, while the academy skews liberal — people drawn to research may be motivated by neophilia.]
  • Same researchers did a Dot Probe Test (measuring speed in identifying a gray dot on a positive or negative image. Speed increases with attentional disposition toward the stimuli). Liberals a bit quicker with positive images, conservatives with negative.

(measuring speed in reporting a feature of an image when flanked by two images congruent or incongruent to the main image. Assumption is that the less you are slowed down by incongruence, the more attentional resources you had for the image.) Replicated typical results: we are all faster with angry faces, for example. Conservative less impacted by the angry faces. Both groups reacted the same to happy faces.
  • What Are You Looking At? 129
  • Eye tracking attentional studies - dwell time. Their research measured "dwell time" - time spent looking at an image. In a study, subjects are shown a group of images. General bias toward negative images. Theorized as having survival value. Conservatives spend a lot more time on negative images and quick to fix on negative images. Some weak evidence that liberals focus more on positive images, but sig. results concerned differentials.
  • Perception is Reality -- But is it real? 133
  • Since liberals and conservatives value positive and negative images in the same way, you might conclude that they see the same world but pay attention to parts of it with different degrees of interest or attention. But Hibbing et. al. are not so sure. In a study, they asked libs and cons to evaluate pos/negly their view of the status quo on six policy dimensions (134). They seem to assess the reality differently, they see different policies at work in the same society, not just attending more to some stimuli. Political difference might not be difference in preference, but in perception.
  • They also did some research on ranking degree of negativity of images and, unlike the Italian research, conservatives did rank negative images more negatively. In another study (135-6), researchers (Vigil) found that conservatives ranked faces as more dominant and threatening than liberals. [Interesting that in both the 1918 pandemic and today's, conservatives resisted mask wearing. Nice coincidence with today's bizarre mask politics story.]
  • You're full of Beans
  • 'Cognitive style in exploration - BeanFest' -- a research game in which test subjects try to earn points by deciding whether to accept or reject a bean with an unknown point value. Based on personality, some subjects are more exploratory (accept more beans and get more information), while others are conservative. Political orientation also predicts strategy. Shook and Fazio see the result as indicative of differences in data acquisition strategies and learning styles. Interesting follow-up analysis based on giving test subjects a "final exam" on the bean values. Similar scores, but different patterns of classification.
  • 139: good summary paragraph: "New bean? What the hell, say the liberals, let's give it a whirl" Roughly equal scores on the game and exam.
  • exploratory behavior and related differences in valuing everyday ethical situations, like forgetting to return a CD. Can you think of a time you attached a judgement to a friend's behavior and then realized it was part of a larger pattern connected to their identity? Being late, tidy, calling back......
  • Differing attitudes toward science and religion. No surprise that science denial comes from the right. Partial effect of our cognitive styles. note p. 140.
