Impact des drogues sur la construction de toiles d’araignée

The experiment is true, but it doesn't really tell us anything about humans. This 4-paragraph NASA publication from 1995 reiterates earlier studies (including those involving LSD) and shows that certain substances administered to spiders deform their webs. https://cvc.li/gESzf https://cvc.li/KtsUG https://cvc.li/JRaru These experiments caused quite a stir, partly because the webs are easy-to-understand illustrations. However, these webs cannot be used to measure the toxicity of a substance on humans, contrary to what the study hoped to demonstrate. In fact, a recent article on the subject warned against comparing the behaviour of spiders with that of mammals, and most especially with that of humans. Correlation is not causation, as they say. https://cvc.li/vcevi To be sure of the effects of these substances on humans, similar studies would have to be conducted on humans, which raises ethical and legal issues, as explained in an article in the ARC Journal of Neuroscience: https://cvc.li/CMZmY
