Despite the difference in methodology, location, and theory, the results attained by Eysenck and Ferguson matched ; simply rotating Eysenck's two factors 45 degrees renders the same factors of Religionism and Humanitarianism identified by Ferguson in America.

Eysenck's assessment of his overall argument is as follows: " There is no hint that the theory is more than a suggestion of how many disparate facts and hypotheses can be pulled together into a causal chain, explaining … the apogee of human endeavour-genius.

The research on sensory-processing sensitivity, however, builds on Eysenck's views on introversion and arousal and Gray's work on the inhibition system.

In psychological theories of personality, the following could be categorized as nomothetic theories: Carl Jung's Psychological Types, Eysenck's three factor model, the Big Five personality traits, and the Myers Briggs Type Indicator.

Eysenck's Encyclopedia of Psychology identifies him as the founder of modern scientific psychiatry, as well as of psychopharmacology and psychiatric genetics.

Examples of publications in which Eysenck's views have roused controversy include ( chronologically ):

While Eysenck's R-factor is easily identified as the classical " left-right " dimension, the T-factor ( representing a factor drawn at right angles to the R-factor ) is less intuitive ; high-scorers favored pacifism, racial equality, religious education, and restrictions on abortion, while low-scorers had attitudes more friendly to militarism, harsh punishment, easier divorce laws, and companionate marriage.

Eysenck's dimensions of R and T were found by factor analyses of values in Germany and Sweden, France, and Japan.

Eysenck's political views related to his research: Eysenck was an outspoken opponent of what he perceived as the authoritarian abuses of the left and right, and accordingly he believed that, with this T axis, he had found the link between nazism and communism.

Central to Eysenck's thesis was the claim that tender-minded ideologies were democratic and friendly to human freedoms, while tough-minded ideologies were aggressive and authoritarian, a claim that is open to political criticism.

Eysenck's conception of ' tough-mindedness ' has been criticized for a number of reasons.

* Eysenck's finding that nazis and communists were more tough-minded than members of mainstream political movements was criticised on technical grounds by Milton Rokeach.

The second factor in such an analysis ( such as Eysenck's T-factor ) is the second best explanation for the spread of the data, which is, by definition, drawn at right angles to the first factor.

Thus, one would expect to find a factor that roughly corresponds to " left " and " right ", as this is the dominant framing for politics in our society, but the basis of Eysenck's " tough / tender-minded " thesis ( the second, " T "- factor ) may well represent nothing beyond an abstract mathematical construct.

Such a construct would be expected to appear in factor analysis whether or not it corresponded to something real, thus rendering Eysenck's thesis unfalsifiable through factor analysis.

Dissatisfied with Hans J. Eysenck's work, Milton Rokeach developed his own two-axis model of political values in 1973, basing this on the ideas of freedom and equality, which he described in his book, The Nature of Human Values.

Despite his criticisms of Eysenck's tough-tender axis, Rokeach also postulated a basic similarity between communism and nazism, claiming that these groups would not value freedom as greatly as more conventional social democrats, democratic socialists and capitalists would, and he wrote that " the two value model presented here most resembles Eysenck's hypothesis.

While factorially distinct from Eysenck's previous R factor, the S-factor did positively correlate with the R-factor, indicating that a basic left – right or right – left tendency underlies both social values and economic values, although S tapped more into items discussing economic inequality and big business, while R relates more to the treatment of criminals, and to sexual issues and military issues.

A recent analysis of survey data using principal component analysis was carried out in 2003 in the UK ; the results of this study yielded the same two dimensions as found by Eysenck's original research: the familiar " left-right " R-dimension that mixes economic issues and social issues, and a second T-dimension that is described as " pragmatism vs idealism.

In Eysenck's terms, they had a " melancholic " temperament.

Eysenck's psychoticism factor incorporates some of the polar opposites of the lower order factors of openness, agreeableness and conscientiousness.

In personality, he is best remembered for his 16-factor model of personality, arguing for this over Eysenck's simpler 3-factor model, and developing tests to measure his primary factors in the form of the 16PF Questionnaire.

Unless one takes refuge in the theory -- however disguised -- that Negroes are, somehow, different from white people, I do not see how one can escape the conclusion that the Negro's status in this country is not only a cruel injustice but a grave national liability.

In constructive set theory, however, Diaconescu's theorem shows that the axiom of choice implies the law of the excluded middle ( unlike in Martin-Löf type theory, where it does not ).

There is no documented evidence for this theory, however, and, the word liti was probably borrowed from 16th-18th century writings in Latin, where the word lituus could describe various wind instruments, such as the horn, the crumhorn, or the cornett.

The Copernican theory of the solar system – that the Earth revolved annually about the Sun – had received confirmation by the observations of Galileo and Tycho Brahe ( who, however, never accepted heliocentrism ), and the mathematical investigations of Kepler and Newton.

The Gaussian theory, however, is only true so long as the angles made by all rays with the optical axis ( the symmetrical axis of the system ) are infinitely small, i. e. with infinitesimal objects, images and lenses ; in practice these conditions are not realized, and the images projected by uncorrected systems are, in general, ill defined and often completely blurred, if the aperture or field of view exceeds certain limits.

Note however that both in algebra and model theory the binary operations considered are defined on all of S × S.

The BCS theory, however, requires only that the potential be attractive, regardless of its origin.

This theory therefore utilises Herodotus ' suggestion that after Marathon, the Persian army re-embarked and tried to sail around Cape Sounion to attack Athens directly ; however, according to the first theory this attempt would have occurred before the battle ( and indeed have triggered the battle ).

Some researchers still advocate a handful of alternative cosmologies ; however, cosmologists generally agree that the Big Bang theory best explains observations.

The physical model behind cosmic inflation is extremely simple, however it has not yet been confirmed by particle physics, and there are difficult problems reconciling inflation and quantum field theory.

In theory, they consist of 11 motorised infantry battalions ; 5 support battalions and 3 backing battalions ; however, the motorised battalions are in reality not operational due to a lack of staff, equipment and vehicles.

Polio does not explain many of the described symptoms, however, and a more recent theory implicates cerebral palsy as the cause, as outlined by Ernestine Leon.

Physical chemistry, however, was one of the first branches of science to study and formulate a " theory of affinity ".

It was not until 1997, however, that a direct experiment, by S. Lamoreaux, described above, quantitatively measured the force ( to within 15 % of the value predicted by the theory ), although previous work van Blockland and Overbeek ( 1978 ) had observed the force qualitatively, and indirect validation of the predicted Casimir energy had been made by measuring the thickness of liquid Helium films by Sabisky and Anderson in 1972.

In theory one can describe compounds that contain the methyl group, with relatively large bond polarity between the carbon and non-hydrogen atom, as salts of this anion ; however in truth most such compounds, if not all, are actually covalent.

What makes the Lettre sur les aveugles so remarkable, however, is its distinct, if undeveloped, presentation of the theory of variation and natural selection.

There is however no firm evidence that even this theory is correct.

A weaker or more moderate form of this political theory does hold, however, that the king is subject to the church and the pope, although completely irreproachable in other ways ; but according to this doctrine in its strong form, only God can judge an unjust king.

From the 1960s, however, such comments abated as the economic theory of maximizing behavior and rational-choice modeling expanded the domain of the subject to areas previously treated in other fields.

Because of the preponderance of evidence in favor of the wave theory, however, Einstein's ideas were met initially with great skepticism among established physicists.

By the late nineteenth century, however, a handful of experimental anomalies remained that could not be explained by the simple wave theory.

The general first-order theory of the natural numbers expressed in Peano's axioms cannot be decided with such an algorithm, however.

Most scholars believe that the community at Qumran that allegedly produced the Dead Sea Scrolls was an offshoot of the Essenes ; however, this theory has been disputed by some, for example, by Norman Golb:
