A University Of Iowa research states that once people form their beliefs, they are not likely to change their minds on the face of new information that clearly proves that their long-held beliefs are completely wrong. They are far more likely to go on protecting and fighting for their beliefs.
Even if the new information is extremely compelling and the person has no choice but to change their opinion, it is a temporary change that reverts back fast.

Feedback And Other's People's Opinions

A direct, upfront message aimed at debunking an existing belief has little effect on swaying an opinion, but if the message first presents the old belief and the justifications behind it, followed by the facts that try to refute the same, a bridge is created, and the impact is greater.

Two studies show us feedback's power in reinforcing beliefs.

If you’re trying to change someone’s opinion , you better be in it for the long haul. According to research, humans are stubbornly set in their beliefs, even when learning new facts that challenge their assertions.

A <a href="https://now.uiowa.edu/2015/11/see-i-was-right">study out of University of Iowa </a>found “that once people reach a conclusion, they aren’t likely to change their minds, even when new information shows their initial belief is likely wrong and clinging to that belief costs real money,” according to a release summarizing its results.

The students had to explain their thinking and analysis behind their forecast prior to trading. Researchers found that even “as the key first weekend box office receipts were reported, prices stayed remarkably stable as traders ignored new value-relevant information and continued to rely on their initial estimates.”

Gruca also had students act as traders but without having them write down their analyses. In essence, they were less committed to them. These participants were more active in their trading when new information was introduced.
