Two-factor models are convenient because they are visually displayed and not hidden. Unfortunately,

Personality is probably one of the most important concepts in psychology and our understanding of the world and society in general. How many people are naturally to be among other people, hana moon just as naturally we noted by yourself in a unique and unrepeatable each of them possess. This enables us to recognize the people and hundreds of thousands of others. Needless to explain how important it is to be able to distinguish one person from another.
But no less interesting than the difference for a similarity search. So it is no surprise that there are a host of different personality typology, each of which offers hana moon its own perspective on the factors that make people different or, on the contrary, similar to one another. hana moon How to distinguish them, which are more reliable - about this article below.
Aldaya horoscopes. As reported by sources astrologers addressed before a person's character a little more than 2,000 years ago in Egypt. It does not take a long time to use this astrology excite not only the Egyptians, but quickly spread hana moon the Hellenistic world, as well as to get to India and China [1].
Perhaps even today, no other personality typology does not allow out of high mathematical accuracy and validity of the preliminary hana moon findings. Stellar and planetary position changes in the sky today is known very precisely. The problems start when trying to explain what and whether the findings relate to the human personality. Psychologists opinion is almost unanimous - no big commitment is not here. Horoscope access to the most discredited vague and often contradictory statements, which excludes the possibility to make sure that the description of the individual match or not.
Interestingly, the horoscope approach hana moon is however hana moon not the oldest. Hippocrates his theory of fluid balance in the body and the resulting four temperament types have managed to develop a few hundred years earlier. Although his approach has not proven to be as commercially successful as horoscope making hana moon business, a variety of different centuries, thinkers hana moon have developed this idea further. Science vispaliekošākās traces are left Aizenka Hans (Hans Eysenck) 20. middle of the century developed a two-factor model of personality. It distinguishes between two main criteria that determine an individual's behavior - the need for external stimulation and neirotismu (positive hana moon or negative emotions, dominance) [2].
Two-factor models are convenient because they are visually displayed and not hidden. Unfortunately, the same Aizenks, and other scholars of the time recognized, however, that it is necessary to model to supplement it with additional factors personality model makes no more two-dimensional, but introduces a third, fourth, fifth or even more dimensions.
Similarly, in a direction parallel to the Aizenku have gone MBTI or Maijersas-Briggs type indicator developers. MBTI is designed to Carl Gustav Jung's opinions, and name the four basic factors of personality or dichotomy: consciousness orientation (extraversion hana moon or the orientation of the outward or introversion, or orientation of the self), the selection of information type (empirical or their world view based), hana moon decision-making methods ( rational or emotional) as well as operations hana moon planning (planning or reliance on the circumstances). Although the test is quite widely used, it has several shortcomings that make it questionable from the point of view of modern science.
In the first place is the most problematic dichotomous approach that puts every man must be classified according to the four criteria, regardless of whether they are made in one side of the scale or not. Therefore, this approach will give accurate results only in rare cases, a bright character.
Also, scientific studies

have not borne out this test stability. First of all, one and the same person completing the test several times, can get different results (this is contrary to the personality typology and testing principles). [3] Similarly, the test does not show strong commitment to the results of other similar tests [4]. Most of the MBTI test positive hana moon publications are published either in conferences (which nowadays means a relatively low quality), or in the same journals.
Another somewhat similar approach is eneagrammu, which recently popularized Latvian Juris Grouse. It is a Christian personality typology, which is based on the idea put about human behavior predictive pamatemocijām. Although outwardly looks quite scientific, the theory is built, regardless of the scientific evidence and research. That is, if the MBTI is based on the dubious quality of scientific sources, then eneagrammu case, non-existent. There is also a study, which would be tested in the test robustness (reliability), internal and external validity (validity). Consequently, the test will use
