If psychology wants the status and rewards of being considered a legitimate science, it needs to make dramatic changes. In the meantime any initial result psychological research produces must be considered not just preliminary, but suspect.

So what social-psychological experiments are bogus?
The most famous problem experiment I can think of is Zimbardo's fake prison, and IIRC the primary objection was that the effect was too strong. He let it go on too long and everyone was disgusted.
Rosenhan's experiment is bogus, yes, but I have to wonder... psychiatrists were condoning lobotomies just 15 years earlier. Is it likely that an entire discipline could turn itself around in that time? (Which doesn't excuse Rosenhan, of course)
I am 100% open to your thesis but would like more data.
The idea that a 'normal person' might become a nazi if ordered by an authority figure was provocative, since it suggested the potential to be a nazi existed in many if not all of us. The disturbing and provocative result of Milgram's experiment seemed to suggest that 'regular people' could indeed become nazis if given orders from an authority figure.
The deceit occurred when the results to publish were cherrypicked from a larger set of experiments performed by Milgram and his team, in which various variables were tweaked. The people from New Haven (home to Yale University) were most likely to comply when given orders from a man dressed like a scientist and were less likely to comply when the orders were given by people in other sorts of costumes. Why? Because people in New Haven had pride in their community, in the university located in their community, and had a belief in the necessity of science. They complied when they were told that compliance would further scientific progress, which they considered to be virtuous. These people were in fact motivated by ideology, just as Adolf Eichmann was. Just as Adolf Eichmann believed in the necessity of the nazi ideology, these people believed in the necessity of scientific progress.
So what did the experiments actually show? It showed that many people are willing to commit atrocities if they believe the ends justify the means. That's not really a provocative result.
