It seems like professor Higashiyama is really conducting research in perception, not so much psychology, as it is understood popularly. He also seems skeptical of what is commonly er perceived as psychological research- and I share his skepticism. FTA:

>> Many studies place importance on overt, conscious actions like seeing and listening. And some psychologists conclude that people are of one personality type or another based on questionnaires that lack evidence, and which are therefore indistinguishable from fortune-telling.

>> “So, people have biases in their understanding,” explains Higashiyama. “The same importance as placed on sight and hearing has to be placed on physical information as well, and conclusions must be based on evidence. Researchers need to be aware of the fact that the field of psychology runs the risk of changing people’s lives.”
