Thinking bias.

Of course, it’s scary to admit that you or your product are somehow not very good. Therefore, communication is filled with sweet speeches and arguments "how cool we are."

As a result, the sugary one-sidedness of the presented facts raises doubts. The interlocutor has the feeling that something is being hidden from him, but he is not aware of what exactly.

Make arguments both for and against. Do not be afraid. In most cases, the opinion about the product is either already formed or anchored by the first impression. Arguments rarely change attitudes towards the subject.

There are many experiments. In Ross and Lepper's study, one group of subjects recruited supporters, and the other - opponents of the death penalty. Everyone was given the same text containing both pros and cons. As a result, the degree of disagreement increased - the participants remembered only those facts that supported their vision of the world.

In political debates, 9 out of 10 viewers consider their chosen politician to be the winner.

We pay attention to information that confirms our point of view and ignore anything that conflicts with our beliefs. We interpret the data in our favor, remember what is beneficial. This confirmation bias is one of the key thinking mistakes. It cannot be avoided. Moreover, the person denies his bias, as he acts unintentionally.

And now we all have a wonderful opportunity to be convinced of this mistake personally. Just try to argue with an active opponent (or supporter) of vaccination, for example.
