Why Intelligent People Use More Drugs
The human consumption of psychoactive drugs , such as marijuana , cocaine , and heroin, is of even more recent historical origin than the human consumption of alcohol or tobacco, so the Hypothesis would predict that more intelligent people use more drugs more frequently than less intelligent individuals. The use of opium dates back to about 5,000 years ago, and the earliest reference to the pharmacological use of cannabis is in a book written in 2737 BC by the Chinese Emperor Shen Nung. Opium and cannabis are the only “natural” (agricultural) psychoactive drugs. Other psychoactive drugs are “chemical” (pharmacological); they require modern chemistry to manufacture, and are therefore of much more recent origin. Morphine was isolated from opium in 1806, cocaine was first manufactured in 1860, and heroin was discovered in 1874.Tetris effect

The Dunning–Kruger effect is a cognitive bias in which unskilled individuals suffer from illusory superiority , mistakenly rating their ability much higher than average. This bias is attributed to a metacognitive inability of the unskilled to recognize their mistakes. [ 1 ] Actual competence may weaken self-confidence, as competent individuals may falsely assume that others have an equivalent understanding. David Dunning and Justin Kruger of Cornell University conclude, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others".
