Statistically reliable, in what sense? That they frequently produce the same outcome on repeated application of the test? That's not a surprise. As a wise man said: the gold standard for repeatable outcome is astrology.
Suppose I make a test and ask questions like "Do you like coffee?" and "Is your favorite color blue?". That would get a very high test-retest reliability. If I then score e.g. +coffee -blue as "intelligent", does that really mean people who like coffee but prefer orange are intelligent?
- knallfrosch 2y ago> Statistically reliable, in what sense? Let's just say that if astrology was reliable, people would follow their horoscopes.
- tgv 2y agoAstrology has a great test-retest reliability. Every time someone tests your sign, the same answer comes out. That's what it means. Same for personality inventories: people's replies don't vary much over time. As astrology shows, that doesn't mean you can draw conclusions.
