:*A Second look at “Morality as a product of Evolution”
+
:*A general challenge of good writing -- '''Getting outside of your head''' -- looking at the writing as if you didn't write it.
:*SW1 Assignment - Review
 
:*Consequentialism - Utilitarianism
 
  
===Summing up Sapolsky: Morality as a product of Evolution===
+
:*Here are a few good writing concepts to look for in the samples on the handout.
 +
::*'''Flow''' -- How well does one sentence follow another?  Do you notice places where flow is interrupted?
 +
::*'''Good starts''' -- Without good introductions and signals of organization and thesis readers are disoriented and confused.  Set context by framing the topic.  Tell your readers where you are going to take them. 
 +
::*'''Efficient writing''' -- Literally, how much you say with so many words.  Awkward phrasing and limited word choice reduce efficiency.
  
:*Some key claims and inferences:
+
===SW1: What's important about your microbiota?===
::*Evolution shapes our bodies, our behaviors, and our ideas (evo-psych)
 
::*Cooperation and coalitions can give us a fitness advantage.
 
::*A problem with cooperation is to not become a sucker.
 
::*This is a problem we can address with values (e.g. it’s a moral problem).
 
::*Values are expectations of others to think, speak, feel, and act in particular ways (and sometimes to refrain from thinking, speaking, etc. in particular ways). (My def. Not in Sapolsky)
 
::*Morality isn’t only about cooperation.  It includes a set of basic social dilemmas and existential problems that affect our ability to thrive.  These are both personal and political problems. (not quite from Sapolsky)
 
::*Morality is a product of evolution in the sense that it is a cultural practice that helps up manage problems that can affect our fitness.
 
  
===Philosophical Moral Theories: Consequentialism -- Utilitarianism===
+
:*'''Stage 1''': Please write an 600 hundred word maximum answer to the following question by '''Saturday, February 4th, 2023, 11:59pm.'''
 +
::*Topic: We've been following science research on the microbiota and connecting that research to practical questions about our diets.  What are some of the general lessons for us coming out of this research and what might it tell us about ''the nature of food and healthy eating''?  In your answer try to give both the "big picture" and highlight some of the more remarkable and interesting results of microbiome research. 
  
:*Brief historical intro to utilitarians: Early industrial society, "social statics" (early efforts to measure social conditions)Utilitarians were seen as reformers.   
+
:*'''Advice about collaboration''': Collaboration is part of the academic process and the intellectual world that college courses are based on, so it is important to me that you have the possibility to collaborate.  I encourage you to collaborate with other students, but only up to the point of sharing ideas, references to class notes, and your own notes, '''verbally'''.  Collaboration  is also a great way to make sure that a high average level of learning and development occurs in the class.  The best way to avoid plagiarism is to NOT share text of draft answers or outlines of your answer.  Keep it verbalGenerate your own examples.   
  
::*Eudaimonistic(about Happiness or Well-Being) vs. Non-Eudaimonistic (Duty)
+
:*Prepare your answer and submit it in the following way. '''You will lose points''' if you do not follow these instructions:
:::*Two views:
 
::::*1) Morality is fundamentally eudaimonistic "in the long run," even if it in particular proximate circumstances in does not always involve positive emotions (includes Utilitarians).
 
::::*2) Morality and moral responses realize disinterested values like reason and justice, that are not related to promoting happy outcomes (Kant / Duty ethics).
 
  
:*'''Fundamental consequentialist intuition''': Most of what's important about morality can be seen in outcomes of our actions that promote happiness and human well-being. (Recall "Intentions-Acts-Consequences")
+
::# To assure anonymity, you must remove your name from the the "author name" that you may have provided when you set up your word processing application. For instructions on removing your name from an Word or Google document, [[https://wiki.gonzaga.edu/alfino/index.php/Removing_your_name_from_a_Word_file click here]].
 +
::# Format your answer in double spaced text, in a typical 12 point font, and using normal margins. Do not add spaces between paragraphs and indent the first line of each paragraph. 
 +
::# '''Do not put your name in the file or filename'''.  You may put your student ID number in the file, but '''not in the filename'''. Save your file for this assignment with the name: '''Microbiota'''.
 +
::# To turn in your assignment, log into courses.alfino.org, click on the “1 - Points” dropbox.

::# If you cannot meet a deadline, you must email me about your circumstances (unless you are having an emergency) '''before''' the deadline or you will lose points. 
  
:*Basic principles of utilitarian thought:
+
:*'''Stage 2''': Please evaluate '''four''' student answers and provide brief comments and a score. Review the [[Assignment Rubric]] for this exercise.  We will be using the Flow and Content areas of the rubric for this assignment. Complete your evaluations and scoring by '''Wednesday, February 8, 2023 11:59pm.'''
 +
 
 +
::*To determine the papers you need to peer review, open the file called "#Key.xls" in the shared folder. You will see a worksheet with saint names in alphabetically order, along with animal names.  Find your saint name and review the next four (4) animals' work below your animal name. If you get to the bottom of the list before reaching 4 animals, go to the top of the list and continue. 
  
::*'''Equal Happiness Principle''': Everyone's happiness matters to them as much as mine does to me. Everyone's interests have equal weight. (Note this is a rational principle.  Emotionally, it's false.)
+
::*Use [https://docs.google.com/forms/d/e/1FAIpQLScOI7j5oxnVd7Sv192fVFYVSiuK5bfwpBLkossVXjC2jir75Q/viewform?usp=sf_link this Google Form] to evaluate '''four''' peer papers. Submit the form once for each review.
:::*Note on method: this is a way to universalize.  Recall earlier discussion about conditions for ethical discourse. Ethics is about figuring out when we need to take a moral concern about something and, if we do, then we take on constraint (conversational): universalizability, equality of interests.
 
  
::*'''Principle of Utility''': Act always so that you promote the greatest good for the greatest number.   
+
::*Some papers may arrive late.  If you are in line to review a missing paper, allow a day or two for it to show upIf it does not show up, go back to the key and review the next animal's paper, continuing until you get four reviews. Do not review more than four papers.
:::*Hedonic version: Act to promote the greatest pleasure ...
 
:::*Classical utilitarian: greatest balance of range of qualitatively diverse pleasures and aspects of well-being.  
 
:::*Preference utilitarian version: Act to maximally fulfill our interest in acting on our preferences.
 
  
::*But what is utility?  What is a preference?
+
:*'''Stage 3''': I will grade and briefly comment on your writing using the peer scores as an initial rankingAssuming the process works normally, most of my scores probably be within 1-2 points of the peer scores, plus or minus.   
::*'''Utility''': pleasure, what is useful, happiness, well-being. 
 
:::*Is the utilitarian committed to maximizing happiness of individuals directly?  A utilitarian focused on promoting utility, might still acknowledge that promoting human happiness is mostly about protecting conditions for an individual's autonomous pursuit of happiness. Consider cases: When does promoting the greater good involve letting people make their own decisions vs. managing or regulating an issue centrally?
 
:::*Conditions for the pursuit of happiness:  Order, stability, opportunity, education, health, rights, liberty.
 
:::*Issue of protection of rights in utilitarian thought.  
 
::*'''Preferences''':  
 
:::*An indirect way to solve the problem of lack of agreement about goods.  Let's maximize opportunities for people to express their preferences.  Positive: pushing the question of the good life to the individual.  Negative: High levels of individualism may reduce social trust.  Lack of action on opportunities to reduce suffering. 
 
:::*Thought experiment: Returning a gun to an angry person.  Is the angry person's preference one that has to count?
 
:::*Cultural contradictions in our preferences: we prefer health, but we also "prefer" to eat the western diet.  Which preference should the utilitarian focus on?  Some preferences are based on bias or prejudice.
 
:::*Need some standard of rational or considered preference.  What a "reasonable person" would do.  Maybe less disagreement about that than "the good".  (Example: Intervening in the lives of homeless mentally ill and suffering.)
 
 
 
====Group Discussion: Assessing Utilitarianism====
 
 
 
:*Consider applying utilitarianism to different kinds of moral problems (from interpersonal ethics to public policy questions)Identify three situations in which you would want to use utilitarianism and three situations in which you would not.
 
  
===Sapolsky, Robert. Behave. C 13, "Morality and Doing the Right Thing" (479-483)===
+
:*'''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: [https://docs.google.com/forms/d/e/1FAIpQLSfukAB_Jmv3GO72xjZiCuPz3ZrVMP1SL-B_WGi171QxFBvPyg/viewform?usp=sf_link]. '''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.
  
:*Is moral decision making mostly reasoning or intuition?
+
::*Back evaluations are due '''TBD'''.
::*The case for primacy of cognition:
 
:::*Lots of examples of reason based rules in law and social institutions.  This kind of reasoning activates the dlPFC and TPJ (temporoparietal junction) - theory of mind tasks.  Suppress TPJ and less concern about intentions! Yikes.
 
:::*Theory of Mind tasks are those involving perceiving and inferring intentions.  Central to social life!
 
:::*Moral reasoning is skewed toward the cognitive in some predictable ways: doing harm worse than allowing it.  commission vs. omission.  tend to look for malevolent causes more than benevolent.
 
  
::*The case for primacy of intuition:
+
===Nix, Chapter 2, "Carbohydrates"===
:::*Problem with moral reasoning (cognitive) view: lots of evidence for intuition and emotion.  We often make moral judgements automatically.
 
:::*Reviews Haidt's Social Intuitionism: "moral thinking is for social doing". The reasoning is mostly to show others what we're doing (and to "advertise" it).  "virtue signaling"
 
:::*Moral decisions activate the vmPFC, orbitalfrontal cortex, insular cortex, and anterior cingulate.  Pity and indignation activate different structures.  Sexual transgressions activate the insula. 
 
:::*In moral quandries, activation of amygdala, vmPFC, and insula typically '''precede''' dlPfc activation.
 
:::*people with damage to the vmPFC will sacrifice one relative to save five strangers, something control subjects just don't do!
 
  
===Haidt, Chapter 3, "Elephants Rule"===
+
:*'''Nature of Carbs'''
 +
::*Carbs are a source of short term energy.  All Carbs break down into sugars during metabolism.
 +
::*Scale of simple to complex.  Simple sugars (monosacharides) don't even require digestion.  Starchs are complex and "slow burning".
 +
::*Limits to the "energy" metaphor:
 +
:::*carb levels and types help regulate other processes like insulin response,
 +
:::*fiber helps with useful bacteria production, appears to reduce colon cancer, helps with bowel function and avoidance of diverticulosis.
 +
:::*carb types and level signal body to break down protein for energy or not. 
 +
:::*soluble fiber binds bile acids, lowering cholesterol
  
*Personal Anecdote from Haidt's married life: your inner lawyer (automatic speech)
+
::*Classes of Carbs:
:*Priming studies: "take" "often"  -- working with neutral stories also
+
:::*Mono and di-saccharides are “simple carbs”.  Glucose is the form that sugar takes in your blood.  
 +
:::*Polysaccarides are found in starches: grains, rice, corn.  Also in plant proteins: legumes. 
 +
:::*Per capita HFCS (high fructose corn syrup) up from .12 tsp daily in 1970 to 11.18 tsp in 2008. p. 15
 +
::*Fibers
 +
:::*Soluble and insoluble - soluble fiber binds bile acids and lowers blood cholesterol.
 +
:::*Insoluable are roughly what the Sonnenbergs were calling “MACs”.
  
*'''Research supporting "intuitions come first"'''
+
:::*Note warning on high fiber low iron-rich diet.  Phytic acid in this diet can cause iron deficiency. You can get too much fiber, but most Americans don't.
  
:*1. Brains evaluate instantly and constantly
+
:*'''Functions of Carbs'''
::*Zajonc on "affective primacy"- small flashes of pos/neg feeling from ongoing cs stimuli - even applies to made up language "mere exposure effect" tendency to have more positive responses to something just be repeat exposure.
+
::*reserve fuel supply is stored as glycogen in muscles [[http://www.nature.com/scitable/topicpage/cell-energy-and-cell-functions-14024533]] and blood sugar.  Roughly 1-2 hours of aerobic exercise.  glycogen also stored in the liver to regulate blood sugar.
 +
::*Carbs keep us from going into ketosis, but as we've noted, you can have a diet based on having your body in a state of ketosis (Paleo).
  
:*2. Social and Political judgements are especially intuitive
+
:*'''Digestion'''
::*'''Affective Priming''' - flashing word pairs with dissonance: "flower - happiness" vs. "hate - sunshine"
+
::*Primarily in small intestine, through enzymes such as amalyse from the pancreas, and from the "microvilli" of the intestine which contain specific di-saccaridases: sucrase, lactase, and maltase.  (digression from p. 26 text box on dairying as textbook case of gene-culture co-evolution.)
::*Implicit Association Test  [https://implicit.harvard.edu/implicit/ Project Implicit]
+
::*Saliva contains enzymes that break down carbs.
::*Flashing word pairs with political terms causes '''dissonance'''. measurable delay in response when, say, conservatives read "Clinton" and "sunshine"Dissonance is pain.
+
::*Glycemic index vs. Glycemic load [https://lpi.oregonstate.edu/mic/food-beverages/glycemic-index-glycemic-load#glycemic-load link for GI vs. GL]
::*Todorov's work extending "attractiveness" advantage to snap judgements.  "Competency" judgments of political candidates correct 2/3 of time. note:
+
::*Note how our bodies are designed to chemically and mechanically break down carbsThere is no need to outsource this to an industrial food!
::*Judgements of competence.  note speed of judgement .1 of a second.(59)
 
  
:*3. Bodies guide judgements
+
::*As we learned from study of the microbiome, you can think of carbs as feeding both you and them (the other 15 trillion organisms you walk around with in your gut). Neither fat nor protein get into the large intestine in significant amounts.  We feed our gut bacteria with carbs.
::*Fart Spray exaggerates moral judgements (!)
 
::*Zhong: hand washing before and after moral judgements.
 
::*Helzer and Pizarro: standing near a sanitizer strengthens conservatism.
 
  
:*4. Psychopaths: reason but don't feel
+
:*'''Recommendations'''
::*Transcript from Robert Hare research
 
  
:*5. Babies: feel but don't reason
+
::*Decrease added sugar to less than 10% of calorie intakeCurrent ly 28 teaspoons of added sugar a day.)
::*Theory behind startle response studies in infants
 
::*helper and hinderer puppet shows: [https://www.youtube.com/watch?v=anCaGBsBOxM Yale Theory of Mind & Baby prosociality]  [https://www.youtube.com/watch?v=a7JbLSIirXI Basic Puppet set up for prosociality studies on babies].  
 
::*reaching for helper puppets  "parsing their social world"
 
  
:*6. Affective reactions in the brain  '''Belief Change'''

  • Note how our bodies are designed to chemically and mechanically break down carbs. There is no need to outsource this to an industrial food!
  • As we learned from study of the microbiome, you can think of carbs as feeding both you and them (the other 15 trillion organisms you walk around with in your gut). Neither fat nor protein get into the large intestine in significant amounts. We feed our gut bacteria with carbs.
  • Recommendations
  • Decrease added sugar to less than 10% of calorie intake. Current ly 28 teaspoons of added sugar a day.)
  • Increase proportion of complex carbs. (But also, following Kessler and the Sonnenbergs, distinguish complex carbs that are in forms that reach your MB.)
  • There’s a good chance you are within the normal range for total carb intake (it's a broad range), but many of you could benefit from shifting the balance toward complex carbs. Think about your "carb profile". Is it tilted toward simple carbs and a high glycemic (index and load) diet? Or are you more invested in complex carbs that travel in rougher textures (with grain structure attached).
  • Check to be sure you are approaching <10% of carbs from refined sugar. 3 2 oz packages of Skittles = 750cal / 168 grams of carbs, but not a good approach! Note this is already more than 10% of calories from refined sugar.
