Check the 'brain deviation' that we didn't expect

Most of us believe that the brain as a video camera will store each 'frame' carefully and reliably.

But in fact, the brain is often attacked by stimuli so what the brain saves is nothing more than a shorthand, with a certain deviation. This contributes to forming different thoughts about each person's past, present and future.

So what phenomena are behind the unconscious deviation of the brain? Let's find out through the following article from the synthesis of Psychology Today.

1. Deviation in "shaping" memories

At some point, the memory not only 'shaped' the information by observing false information, but also due to the 'ease' of memory. This makes many old moments replaced "logically" with external information.

To draw this conclusion, the experts conducted an experiment. They asked the audience to see a series of slides about the car crashing into pedestrians. Half of the volunteers looked at the photo with a 'Stop' sign , while the rest were shown a 'deceleration' picture when the car crashed.

Next, half of the candidates will be asked about the signs they saw, the rest will say the feeling about the sign they didn't see. As a result, 41% of the respondents on the sign were not supposed to think they saw the sign. This proves that, with only the suggestion from the question, the brain has formed a completely different memory.

Another experiment showed that the possibility of 'shaping memories' could occur. Candidates were shown four videos of crimes, each of four minutes of video: robbery, liquor store robbery, warehouse theft and a violent incident.

After a week, the candidates were asked to fill in a multiple-choice questionnaire consisting of 10 questions about the event that they saw and 10 questions about the drug trafficking incident they have never seen. As a result, 64% of respondents said they could remember the video about the drug trafficking.

Even when asked to describe this hidden video, 75% of volunteers provided detailed information from the other 4 videos, while 25% provided information . completely new.

In another experiment, the researchers requested a list of childhood events. Two weeks later, the interviewed candidates described in detail an event in a minute and as many as 24% of people confidently described events that they had previously claimed, never happened.

These experimental results indicate that memories can be controlled by adding false information . Besides, memories can be replaced in unconsciousness only by imagination.

2. Late cognitive trends

The brain is always automatic and unconscious, making events and experiences around it meaningful. This makes unexpected events no longer unexpected, even becoming inevitable.

This phenomenon is called 'hindsight bias ' or 'hindsight bias' . When encountering this error, many people believe that they see events that have been predicted with high probability, despite the actual probability of past events is very low.

The memories that predict things will disappear so many people will be confident that they have predicted it from the beginning - like the 2008 financial crisis, or the election results .

This bias causes you to believe that the 'seemingly' event is easy to guess and explain, thereby relieving stress on the brain. But this discourages thinking to find a solution and greatly influences the results of future behavior.

According to experts, the "late bias" only occurs after you have failed. This prevents us from thinking against alternative behaviors to ensure success from past events.

3. The "prejudice" impact on the brain

According to Timothy Wilson and Daniel Gilbert, people always overestimate how powerful an event will drive their lives and emotions.

When thinking about a future phenomenon, we have to imagine and paint a picture of it. This is not easy because the event never happened. It is because you have not experienced it so it makes you misunderstand the problem - in other words, creating a picture so far away from reality.

Suppose you are imagining and making predictions about how you will experience your wedding day. It must be a beautiful setting, every moment is perfect and you are happier than ever.

But the wrong picture doesn't take into account incidents such as weather, guests, even people who break up . The reason this is because every time we imagine the future, we tend to be simple. chemistry, feeling and forgetting that experience and emotions are very complex.

According to experts, "impact bias" is a common mistake when shaping a situation before making a decision. When comparing two perspectives, people often focus on the differences, not the similarities.

Suppose a person moves because he wants to change his life. When comparing two regions, people often only care about differences such as weather, costs . but forget what makes them want to move is social life.

However, this brain 'bug' also contributes to 'cooling' our nervous system like reducing stress load. But at the same time, it prevents decision making that can make people really happy.

4. Deviation in affirmation

When you think that something is right, you will just look for evidence to support that thought. This is the brain's fault and also the 'shortcut' to let us think quickly and 'automatically' instead of careful consideration.

Confirmation bias is also unconscious. This error makes us think and evaluate ideas in a logical way, but in reality it is not.

Experiments by two scientists Ivan Herandez and Jesse Lee Preston on two situations that are definitely biased to confirm will happen: another death sentence and sentence from the jury (researchers give bias to judgment from a jury).

They found that the processing speed of each candidate varies according to the level of effort when reading. Clearly written presentations help readers quickly, make conclusive conclusions that show the fast processing of information and appear biased errors, while cases are given for writing with hard fonts read, or unreasonable sorting pages, give more analytical and objective results.
