Brain Preference For Past Experiences Can Lead To Biased Decisions

The human brain remains an object of interest for many researchers, as there are many trait that remains unexplained. A new study conducted by a team of research might explain why humans are more likely to make faulty decisions in some cases.

Previous research has showed that the brain prefers to be exposed to experiences that will have a happy ending. It will also tend to undermine the importance of negative events that happened in the past, a tendency that becomes more pronounced as time passes.

Biased brain

When humans need to make a decision to regions of the brain will compete. One of them would convince the brain that experiences which ended well are more beneficial even if they started badly, while the other will undermine experiences that started well but didn’t end well.

As the brain is more focused on the final moments of memory, one would feel tempted to go to a restaurant where they enjoyed a good meal in the past even if they had to wait for more for it or there were other inconveniences before the food arrived.

It is important to pay attention to what we remember when making a decision since the default temptation of chasing a happy ending can favor the tendency to make a bad decision. Know as the happy end effect; this trend is based on past decisions that ended well, even if the context wasn’t as great as it could have been.

While some of the decisions can be quite minor, others can lead to long-term consequences, which are far from being pleasant, and the brain will be convinced that the right choice was made in time. The study also challenges a past belief, which argued that poor decisions are encouraged by the amygdala, as it appears that overall decision-making mechanics are tied to the region.
