I don’t want to say how, but I know Dr. Wansink and I can say everyone here would find him a charming and sincere man. He is the sort of person who will be totally honest with you when you ask a question and you can see how he lights up from just having the opportunity to be with you.

However, I can see how he could choose to ignore data that might not seem supportive or relevant, but then, I can see how this would be an easy choice for so many researchers. Unfortunately, marketing personalities are not often rigorous personalities. “Rigor” talent goes to computer science, statistics, finance, accounting, medical, and engineering disciplines.

Thank you for the insight into the person, Dr Wansink.

It may be human nature, for workers to push in a direction that the leader would appreciate.
Also, there can be nonverbal communication.

Success is a delightful narcotic. "Winning isn't everything; it's the only thing"

Stopping an experiment when a p-value of .05 is achieved is an example of p-hacking. But there are other ways to do it — like collecting data on a large number of outcomes but only reporting the outcomes that achieve statistical significance. By running many analyses, you’re bound to find something significant just by chance alone.
