Please help Why do people hold on conspiracy theories, even when there is evidence that might prove them wrong

Typically those people dont trust the government, and feel the "evidence" could be fabricated. but let's say they do trust the government, when someone believes something heavily, they have hope in said thing. for example. their are some evidence to argue certain parts of religion, yet religion can also has evidence to prove itself to be real. I hope I explained it good enough.

its repetition emphasizing that the chain is his own. sorry if i am wrong.

samuel gompers was an extremely important person in the american labor movement, being him an employee all his life he devoted himself to fight for the rights of his pairs, he believed they all had the right to have better thing and that they all were working for them but the factory workers were greedy, ambitions and socialist people for him who he didn't have a good concept of.

he gave so many speeches and led so many strikes and protest to fight for equality which he considered employers didn't want to accept, so he had an absolutely negative opinion of them.
