Does Your Blood Type Affect Your Personality?

I find an article "Does Your Blood Type Affect Your Personality?" which said,

There have been numerous studies that have attempted to use research and statistics to study the linkage between blood type and personality.  Unfortunately, research has proven to be inadequate and restricted, as statistically inappropriate measures, methods, and samples have been utilized.  This has resulted in the failure to show any statistically significant correlations between blood type and personality. Due to this fact, blood type personality theory is largely dismissed by the scientific community.

Methods: We surveyed 303 undergraduate students using a questionnaire that tests their basic understanding of psychology, view of psychology, and expectation for psychology prior to their specialized education.
Results: We found that respondents (1) had a limited understanding of the objects and methods of psychological research, (2) had a biased view of psychology, undermining the scientific aspects of psychology [as the image of psychology, "nonscientific", "humanities" and "friendly" factors were prominent], and (3) tended to overestimate the effectiveness of psychological solutions on interpersonal problems.
Conclusions: The results indicated that curriculum for the elemental psychological education should be reorganized and reformed at the university.
