It is important to separate wrong results from the person who does or publishes them. There's always chance that some research fails to reproduce. Proper controls and methodology reduce it, but it's still there. Especially in fields where the science just begins to understand the basics and where the matters are as complex and diverse as human behavior. We shouldn't be afraid to question the conclusions if they don't reproduce because it might imply that it was "conjecture or pseudoscience". Sometimes it is, but often it isn't - it's just this particular theory proven to be not true. Happens all the time to the very best of scientists.
