Contributions spontanées

Honesty Box

– In a somewhat spookier example, researchers staged an experiment in a workplace kitchen wherein employees would routinely make themselves tea or coffee in exchange for a fee that they would drop in an ‘honesty box’

– In the first stage of the experiment, the researchers planted a picture of a flowerpot in the room, while in the second stage of the experiment they replaced it with a picture of a pair of eyes

– The two pictures were then alternated back and forth each week, for a period of ten weeks

– Finally, the researchers compared how much money was left in the honesty box across the 2 situations in the experiment.

– Here’s Kahneman to explain the results: “no one commented on the new decorations, but the contributions to the honesty box changed significantly…

– On average, the users of the kitchen contributed almost three times as much in ‘eye weeks’ as they did in ‘flower weeks.’ Evidently, a purely symbolic reminder of being watched prodded people into improved behavior. As we expect at this point, the effect occurs without any awareness” . This is a very eye-opening example of how System 1 can influence System 2, and also hints at the frightening ways that System 1 might be exploited.

Cognitive Bias

• Many classifications

– We took an “actionable” one , inspired by the DQ 101 Stanford Mooc (Karl Spetzler)

Subitization

• subitization

• (psychology) The process of, or act of, glancing at a group of a few objects and knowing how many there are without actually counting.

Group think

• Voyage a Abilene

Page 32: Biais cognitif, creativite et Design thinking

Voyage à AbileneQuatre adultes, un couple marié et les parents de la femme, sont assis sous un porche dans une chaleur abrutissante dans la petite ville de Coleman, au Texas, à environ 53 miles d'Abilene. Ils sirotent tristement de la citronnade, observant le ventilateur souffreteux et entamant de temps à autre une partie de domino. À un moment, le père de l’épouse suggère qu'ils se rendent à Abilene pour se restaurer dans une cafétéria. La femme dit “ bonne idée”.Le gendre pense que c'est une idée folle; que ca va être long et étouffant, mais pense que ses idées sont contraires a celles du groupe, et n’ose pas contrarier sa femme qui voit si peu ses parents. Il dit “super, j espère juste que ta maman veut y aller”.Les deux femmes ne semblent pas opposées à cette idée et voilà tout ce petit monde entassé dans une Buick sans air climatisé, qui soulève sur le chemin des nuages de poussière. À Abilene, ils mangent un déjeuner médiocre dans un endroit glauque et reviennent à Coleman épuisés, suants, et peu satisfaits du périple. Un d’entre eux dis de manière malhonnête “c était super, n est ce pas”. La belle mère dit alors “ en fait j aurais préfère rester a la maison, mais je suis venu avec car les 3 autres avait l air enthousiaste”. Le mari dit alors, “ je n avais pas vraiment envie d y aller; mais j essayais de vous satisfaire”. La femme dit “ je suis juste venu avec pour être avec vous. J aurais été folle de sortir par une telle chaleur”. Le beau père dit alors qu’il n avait suggéré ceci que parce que il pensait que les autres s ennuyait”

priming

• Video

• http://m.youtube.com/watch?v=HRAKt0GakJM

• “the ‘Florida effect’ involves two stages of priming. First, the set of words primes thoughts of old age, though the word old is never mentioned (“worried,” “Florida,” “old,” “lonely,” “gray,” “bingo, ); second, these thoughts prime a behavior, walking slowly, which is associated with old age. All this happenswithout any awareness. When they were questioned afterward, none of the students reported noticingthat the words had had a common theme, and they all insisted that nothing they did after the first experiment could have been influenced by the words they had encountered. The idea of old age had not come into their conscious awareness, but their actions changed nevertheless”

Page 47: Biais cognitif, creativite et Design thinking

Framing

• http://m.youtube.com/watch?v=Ng9V2JneJ68• “the five-year survival rates clearly favor surgery, but in the

short term surgery is riskier than radiation”• When it came to the short term risks of surgery, though, • half of the doctors were shown stats that referred to the

survival rate (which is 90% after one month), • while the other half of the doctors were shown stats that

referred to the mortality rate (which is 10% after one month) .

• Here’s Kahneman with the results: “you already know the results: surgery was much more popular in the former frame (84% of physicians chose it) than in the latter (where 50% favored radiation).

Page 48: Biais cognitif, creativite et Design thinking

Brainstorming: the 65’s way

• Focus on quantity

• Withhold criticism

• Welcome unusual ideas

• Combine and improve ideas

Page 49: Biais cognitif, creativite et Design thinking

Brainstorming: the challenges

• Blocking

• Collaborative fixation

• Evaluation apprehension

• Free-riding

• Personality characteristics

• Social matching

Page 50: Biais cognitif, creativite et Design thinking

• PS: a bit of Mess is good for creativity (Priming Divergent rather than order = convergent)

• http://consulting.openbooklearning.com/misc/damage-results-from-linking-creativity-only-to-divergent-thinking/

Divergent and Convergent Thinking

Page 52: Biais cognitif, creativite et Design thinking
Page 53: Biais cognitif, creativite et Design thinking

You already knew biases…

• Some bias are helpful in convergent and « harmful » in divergent and vice versa,

– e.g. : association, priming, defence of the mindset, framing…

Page 54: Biais cognitif, creativite et Design thinking

Removing Bias ?

• Most classical techniques discovered in brainstorming, CPS, DT are in fact either usingbias or going around bias to mitigate theireffects…

• One cannot really remove biases, because weare human.. But we can be aware of theireffects… and knowingly either use them of defend against them..

• This is .. Maturity …

Design thinking

• http://fr.wikipedia.org/wiki/Design_thinking

• Le Design Thinking est une méthode de créativité et de son management qui se veut une synthèse entre la penséeanalytique et la pensée intuitive. Il s'appuie beaucoup sur un processus de co-créativité impliquant des retours de l'utilisateur final.

• Loss aversion

• Confirmation bias

• Sunk cost fallacy

• Anchoring bias

• Overconfidence bias– Above average : all the children are above average

– limited to “easy” tasks in which success is common or in which people feel competent. For difficult tasks, the effect reverses itself and people believe they are worse than others

– Strikes, lawsuits, and wars could arise from overplacement.
