What I have been thinking about was, given that priming influences decisions made not much long after the stimulus, whether it can also influence beliefs. When you first encounter a proposition you usually sort it into the categories of believed or disbelieved statements, and it can be viewed as a special type of decision. I admit that whether beliefs formed under the influence of priming wouldn't revert in the long term is a different question.

A related question is: Do people later regret their decisions more often if they made them under priming? I know that people are unaware of being primed, but could somehow realise that their decision was wrong. Is there some study about this aspect?
