If you created a believe it is gonna stick.
Stanford social psychologist Lee Ross' classic 1970s studies found that people's beliefs persisted even when evidence to support them was eliminated.
In these experiments, participants were first provided with evidence that supported a particular belief. For example, they were given the task of guessing which suicide notes were genuine and then provided with feedback about their accuracy. People drew inferences from the feedback they received; those who had been given positive feedback scored themselves much higher on empathy than those who had been given negative feedback. However, when the feedback was discredited by telling participants that there had been a mix-up, their beliefs about their empathy were still maintained. Even when the evidence was eliminated, those who had previously raised their opinions of their own empathy still maintained their new belief, as did those who had been convinced that they were not very good at guessing other people's feelings.
