Background

I have come across a number of personality theories. There are even disciplines of personality theories, dividing these theories according to the assumptions they are based upon. The most accepted/used theories seem to be Big 5 and Myers BriggsMyers–Briggs Type Indicator (MBTI). However, I assume these theories too use traits to determine people's personality types among peopletoo.

For example, the five traits Big 5 uses to distinguishtraits seem to be of very limited scope. Also, measuring between traits like Introversionintroversion and Extroversion,extroversion using some random questions which have polar opposite choices seems to be a fitting into a box sort of thing. There seems to be no scientific method while testing to determine whether people fall into one region or other - for all the defined traits.

By scientific determination, I mean one could use methods like the one laid out in "Cerebral Blood Flow and personality: A Positron Emission Tomography Study" to determine between, say, Introversionintroversion and Extroversionextroversion traits. I am not sure whether the other traits have such methods researched enough to distinguish between them.

Question

  • Are there any personality theories that are based purely on scientific grounds?

  • Are there any existing personality theories (that are being researched), that could one day be backed up by scientific research? I think the Big 5 might come under this category. But, but any evidence to the above regarding any theory will be appreciated. Thanks!

6 fixed grammar. title: methodology->method (methodology is a system or a study) removed "subjective" which, ironically, is itself subjective. Personality need not be capitalized (it is a common noun)

4 changed the question to focus more on personality theories in general, and improved foucs on Big 5. The original question has been divided into five parts (including this one) - links to which are available in the comments.
