Hi all, I'm back.
During the holidays I heard that really struck: We all know that we have a blind spot , but rarely do we wonder why do not walk with a "hole" in our vision. Our head somehow fill that space and so we walk through life without thinking about it we do not.
also have blind spots in our way of judging situations, thinking about the probability of something, and as our friend would say Spiderman (the movie) sometimes our mind plays tricks us.
What I have wanted to do today is to tell of some who call me particular attention, hope you like:
Availability: claims that we use the ease with which we can think of examples or cases [of a situation] the judge as more or less likely. Depending on how available (How "at hand") have something in our mind what we judge as more probable. Availability is an imperfect indicator because recent events are remembered more easily, the media shows us every day deaths of people assaulted and walk more frightened of assaults being that, for example, more young people die in traffic accidents that assaulted. Then you should be in great regard for political candidates for any office implementing good preventive measures in this field. Anyway.
Hypothesis Testing: usually serve only to information that proves our hypothesis. This not only validated our hypothesis is that they also ignore the information that validates an alternative hypothesis. Otherwise "typical" is presented that is the time to ask questions that have to do with the hypothesis: \u0026lt;\u0026lt;[...] tend to generate and select questions compatible with the hypothesis.>> Questions that are compatible with the hypothesis for the way in which they are drafted make it more likely to respond positively. Moreover, the affirmative answer to questions related to the hypothesis itself does not make the alternative hypotheses are wrong.
regression effect the average: phenomenon whereby if someone gets too extreme a result, tend to get a less extreme and closer to the average post-event. This is very common (at least for me), the funny thing is that often when someone has gone very well and then things go wrong we tend to blame the regression to the mean "could not go so well yéndole" .
Simulation: We judge the probability or likelihood of an event based on the difficulty or ease with which the mind can construct scenarios that occur. Many times I have seen: We thought that something is very difficult or not going to be but when we visualize the possible positive scenario we relax.
I leave it up to here but not without prior reflection: in many psychology courses it comes to these biases and leave them as the bad guys, but I do not think that is the intention of the teachers. Without these Heuristics could not act in the world and our ability to process information is limited and these shortcuts of the mind simplify everything so that the infinity of possibilities overwhelm us. The trouble is that these shortcuts often lie to us hahaha. so that's why I put them here.
Another thing: this is all too summary, if you're interested read more about it. Do not take it as truth absolute and now they know this is not thinking that the rest walk thought wrong and now you think about it. The truth is that getting rid of the mental shortcuts is quite difficult.
My source to vary is the book "Social Psychology of the Americas" The main theory of this is Kahneman and Tversky (1982), which is known as "bounded rationality", here a lot longer text for those interested the subject. Thanks for Claudio Fuentes (Professor UDP) to provide students this document:
