How should groups make decisions?

I take attendance by having the students answer a question. Today's lecture was on Arrow's Impossibility Theorem so I quite reasonably asked:

How should groups make decisions?

I framed the question as a group deciding where to go for dinner, given the individual ranked preferences of each person over all the dinner options. So one student, confronted with impossibility, wrote, "just starve, we're going to die anyways. ^_^". Another summarized national exhaustion with "I don't like decisions" and yet another echoed the first with "why bother, we will all die anyways".

Others took a more whimsical approach:
  • anarchy
  • define a "mom"  friend, listen to them
  • attendance sheet surveys
  • attendance sheet popular vote
  • separation of power
  • choose 50 US residents at random (with replacement), repeat sample 100,000 times, choose most popular winner
  • a long and indecisive debate
  • only consult those with the loudest voices
  • not first past the post
  • dictatorship
  • elect a dictator
  • math
  • select the most privileged person, ask them
  • compromise
  • hand raising
  • someone should make an impassioned speech
  • oracles
  • trial by combat
  • long discussions
  • flip n coins
  • throw questions into the void and wait
  • Quaker Process (Organized Consensus)
  • no groups; return to hunter gatherer society
  • debate
  • pick the best one
  • rolling dice
  • compromise
  • capitalism!!
  • by assuming I'm always right
  • alphabetically

A subset of students were excited by the idea of a dictatorship, but wanted to further specify which dictator in particular:
  • politburo with Josif as head
  • establish [student in class] as dictator
  • Option 1: oligarchy consisting of Ina Garten, Alex Guarnaschelli, and Amanda Freitag
    Option 2: The Purge

In the margins of the attendance sheet, students sketched political signs and placards and then later students annotated them (by adjusting the name) or voted (by writing "+1" nearby).

I don't know what a "complementary probabilistic majority" is, but it sounds neat. Gold star for piquing professorial curiosity.

By popular vote, "compromise" was the only method which received more than one vote. But several other votes were similar (the above, two voting to "die anyways", and several picking debate/discussion).


This post's theme word is consonance (n), "agreement or accord" or "a combination of sounds pleasing to the ear" or "the repetition of consonant sounds, especially at the ends of words, such as st in the phrase first and last." Consonance and assonance together underlie many tongue-twisters.

What plague do you wish on your enemies?

I take attendance by having the students answer a question. As we near the end of the semester, I am asking the truly deep and personality-revealing questions:

What plague do you wish on your enemies?

Traditionalists:
  • darkness
  • bubonic plague
  • bugs (pun intended)
  • boils!!
  • locust swarm
  • black (bubonic) plague
Tradition with a bit of a twist:
  • really cuddly locusts
  • flaming dog rain
  • hairless cats
  • bees?
Dark or too honest:
  • endless Mondays & cumulative finals
  • long Sharples lines
  • my life
  • misery
  • life
  • perspective
  • classes where you learn nothing & never get any grades back
Not really feeling malicious today:
  • teddy bears
  • plague them with love
  • none
  • happy and healthy lives
  • pass
  • N/A
  • no plagues
Earnest and unsortable plagues:
  • having to deal with people like them
  • P=NP nightmares
  • man-eating snowmen
  • piece of hair always stuck in mouth
  • very droppy icicles form around them and often lightly stab them
  • eternally dry eyes
  • your face turns into a plague doctor mask with the beaks and stuff
  • a case of mitosis, aggressive osmosis

I am fond of "piece of hair always stuck in mouth" as a low-level continual irritation which is not directly harmful, but definitely the sort of thing to wish on an enemy. The icicles also earns points for convoluted (preplanned?!) detail. However, the winner must be "eternal ear wax" which is something we all have, but I guess as a plague it would be unusually bountiful?


This post's theme word is vouchsafe (v. tr.) "to grant or give something as if as a favor" or (v. intr.) "to condescend." I vouchsafed to post the homework several days early, to raucous applause.
