Personality profiles are fundamentally flawed and have historically been pure voodoo. Read up on the MMPI. The intent of a psychological profile has always been intended to be a diagnostic tool to evaluate a person seeking help. Psychologists love these profile tools because it puts all the effort on the patient to be pigeonholed into a particular pharmacological protocol.

To ask survey participants to evaluate their personal qualities in the context of considering a speculative investment, not only does this color the results of the diagnostic profiling tool but the results are highly predictable regardless of the population.

The only thing this study tells us is there is nothing new under the sun (other than Bitcoin) such there are psychologists for sale that are willing to erode their professional credibility in order to degrade any individual that dare challenge the corrupt central banking fiat money system.
