Introduction
This page is the third part of a study of articles.
Blood type and personality by Mary Rogers and A. Ian Glendon
A Pilot Study Using AI for Psychology: ABO Blood Type and Personality Traits by Masayuki Kanazawa
The five factor model
The five factor model is the most widely accepted way to measure personality.
Five factor model
Divides personality into five aspects :
extraversion
neuroticism
openness to experience ( or intellect )
agreeableness
conscientiousness
Each aspect is dependent on genetics to a certain point. Genetics determine :
- 40% of neuroticism
- 53% of extraversion
- 61% of intellect
- 41% of agreeableness
- 44% of conscientiousness
They are also correlated between each other meaning it is possible to predict, to a certain degree, the score of one aspect from another.
The first article was only the second ever published article to look at blood type, gender and the five factor model.
Optimism was also included using the revised life orientation test ( LOT-R), making it the first to include optimism in addition to the 3 measures above.
Results
The experiment found correlations between the different variables ( the five factors and optimism ).
It also found some evidence for relation of neuroticism being slightly higher in women than men and an effect of gender on extraersion.
However, no relation was found between blood types and any aspect of personality.
The second article : AI supports the relation ?
On the other hand, the second article was able to find a relation.
They used AI and taught it to determine the blood type of people using their personality.
The author of this article says that the machine was able to find the blood type of people at a rate higher than chance.
This was also in the case of looking at people who didn’t believe or know about the blood type and personality relation.
However, again, this study wasn’t perfect. It didn’t have the same number of people in each blood type.
Instead it had a similar proportion to that of the Japanese population as it was done with Japanese participants.
