MORE IDEAS FROM THE ARTICLE

  • Researchers extract a lot of false certainty from data which is used to study a particular hypothesis, due to their myopic thinking, confirmation bias, and other cognitive assumptions that they aren't even aware of.
  • Many researchers believe in small samples of data as if they stand for the whole of the population, and this can lead to unpredictable consequences.
The Eye Poster Experiment

It points out our irrational bias and behavior towards our surroundings. How people succumb to irrational beliefs was demonstrated in an experiment at a University Kitchen.

It found out that if there was a poster with eyes put up near the kitchen counter, then people were more likely to pay for the food, subconsciously taking those eyes in the poster as someone looking at them.

The Anchoring effect is a phenomenon studied in the art of persuasion and influence.

It states that people tend to register the first piece of information that they get and 'anchor' it in their minds subconsciously. This makes them compare the second piece of information they get with the anchored information in their minds, automatically.

Thinking, Fast and Slow

IDEAS

Our brains have two "systems" that complement eachother, with their own capabilities, limitations and functions.


  • System One is fast, automated and precise, but can be easily tricked and has a small working window.
  • System Two is slower, can make complex thoughts achieved in a specific algorithm and takes control over it's brother when he needs to with it's long but limited attention buffer.
Note Taking

Students who take notes during a lecture or presentation achieve more than those who just passively listen.

Note-taking makes one's attention focused on the ideas being discussed, and also leads to a review of the lesson being taught. It is a good idea to take complete and detailed notes, as one study shows that the more note the students take, the higher is their achievement. Omitting details or examples is common among students, but is not advisable.
