“The test’s authors (H. J. Eysenck & Eysenck, 1994) justify the low reliability of scores on the P scale by stating, It must be remembered that the P scale taps several different facets (hostility, cruelty, lack of empathy, nonconformism, etc.) which may hold reliabilities lower than would be true of a scale like E, which comprises largely sociability and activity items only."

History

Some of the questions are too vague and should be more specific to gain a more accurate result.

For the full version all you get is a manual to go over the questionnaire there is no outside opinion and this can lead to an incorrect conclusion.
