Verified step by step guidance

1. Understand that Hans Eysenck proposed specific criteria for identifying personality factors in his trait theory, focusing on scientific rigor and biological basis.
2. Recall that Eysenck emphasized that a factor must be psychometrically reliable, meaning it should be consistently measurable through tests and assessments.
3. Recognize that Eysenck also required factors to have biological correlates, linking traits to physiological or genetic evidence.
4. Note that Eysenck believed factors should be universal, meaning they must be found across different cultures to ensure they are fundamental personality dimensions.
5. Identify that 'the factor must be socially desirable' is NOT one of Eysenck's criteria, as social desirability is a bias or preference, not a scientific criterion for defining a personality factor.
