reading Kahneman

Про общее и частное: 


Subjects’ unwillingness to deduce the particular from the general was matched only by their willingness to infer the general from the particular.


Про меньше - больше:


“They constructed a very complicated scenario and insisted on calling it highly probable. It is not—it is only a plausible story.” 


“They added a cheap gift to the expensive product, and made the whole deal less attractive. Less is more in this case.”


Про то, как не бывает "маленьких рисков":


A basic limitation in the ability of our mind to deal with small risks: we either ignore them altogether or give them far too much weight—nothing in between.


Про планы:


Plans are best-case scenarios. Let’s avoid anchoring on plans when we forecast actual outcomes. Thinking about ways the plan could go wrong is one way to do it.


Краткое определение эвристики:


The technical definition of heuristic is a simple procedure that helps find adequate, though often imperfect, answers to difficult questions. The word comes from the same root as eureka.


Про повторение:


Very little repetition is needed for a new experience to feel normal!


И главное - про связность! (жирный шрифт - мой)


The participants were fully aware of the setup, and those who heard only one side could easily have generated the argument for the other side. Nevertheless, the presentation of one-sided evidence had a very pronounced effect on judgments. Furthermore, participants who saw one-sided evidence were more confident of their judgments than those who saw both sides. This is just what you would expect if the confidence that people experience is determined by the coherence of the story they manage to construct from available information. It is the consistency of the information that matters for a good story, not its completeness. Indeed, you will often find that knowing little makes it easier to fit everything you know into a coherent pattern.
