We love to agree with people who agree with us.
That's why we primarily attend forums,
where people who share our political views,
and communicate with people, tastes and opinions which are similar to ours.
We are unpleasant individuals, groups of people or sites,
that make us to doubt their own right - a psychologist
Skinner called this phenomenon "cognitive dissonance».
This selectivity and leads to "confirmation bias» -
we often subconsciously perceive only the information,
which "feed" our existing judgments, ignoring or rejecting everything,
that they conflict and threatens to destroy the familiar image of the world for us.
Internet, by the way, only reinforces this trend.
Intra bias - a phenomenon similar to the confirmation bias, which was discussed above.
This is a manifestation of our innate need to "feel part of a team».
Oddly enough, this need is related to the hormone oxytocin - the so-called "love molecule».
This neurotransmitter, on the one hand, helps us to build close ties with each other,
on the other - it produces the opposite effect with respect to those who are left out of our "circle».
He makes us suspicious, inspires fear and even arrogance towards strangers.
Finally, intra-bias leads to
overestimation of abilities and values of our own group and underestimate those,
about whom we are, in fact, have no idea.
This tendency to attach great importance to the events already accomplished,
confidence that they can somehow influence our future.
A classic example - the coin toss. If five consecutive falls tails,
the likelihood that the next fall the eagle in our consciousness increases.
In fact, it still remains 50/50.
Roughly the same runs trap "positive expectations" inherent gamers.
They think that after a few losses luck just
I must turn to face them and have the next game they will bring a huge jackpot.
Similarly, work and confusion about the "band of luck».
Each of us can remember a single case when, after buying something unnecessary,
unemployed or prohibitively expensive tried to persuade himself that "still it was worth it».
This is the "post-shopingovogo rationalization" - built
in our awareness program with which we can feel
a little better after we make any obvious nonsense.
This phenomenon is also known as "consumer Stockholm Syndrome" - a subconscious desire
in that whatever was to find an excuse irrational buying - especially if it has cost dearly.
Neglect of probability
Very few of us are afraid to get into the car, but most can
admit that experiencing the thrill when coming on board the aircraft.
Flight, no doubt, it is unnatural for a man
condition and is associated with danger.
At the same time, almost everyone knows that the probability die
in a car accident many times greater than in a plane crash.
And yet, our brain refuses to accept this relationship
(statistically likely to be killed while traveling by car - 1/84, by plane - 1/5000).
The same phenomenon causes us to be afraid to die at the hands of terrorists,
and not think about much more real danger -
fall down stairs or accidentally poisoned, for example.
