I want to take a real IQ test but I have no idea where to start. Every time I search online I get flooded with free quizzes that take 5 minutes and tell everyone they are a genius. I know proper clinical assessments exist but those seem expensive and hard to access. What are my actual options for getting a real score and how do I tell the difference between a legitimate test and one that is just going to waste my time?
There are basically three tiers. Free online quizzes with no real norming that flatter everyone, full clinical assessments like the WAIS that are precise but expensive and hard to access, and legitimate online assessments in between. RIOT IQ falls in that middle tier, covering 15 subtests across 6 CHC domains with actual psychometric foundations and proper norming behind it. That gives you a real score and a detailed cognitive profile without the clinical price tag.
The dead giveaway for a fake test is that it takes under 10 minutes and gives you a score above 130 
Real cognitive assessment takes time because g only emerges reliably when you sample across enough different ability domains. If it felt easy and quick it was not measuring your intelligence, it was flattering your ego.
