There was an article reported today on CNN’s site, discussing a recent scientific study in which high levels of IQ are linked to the propensity to use drugs. Immediately, the people who have responded have started making the usual faulty scientific connections, such as “that proves it! Using drugs leads to a higher IQ!” One responder, named JeffinIL, states specifically, “I never realized I went to high school with so many geniuses.” As usual, someone took the conclusions and then tried to return the conclusions to the hypothesis, essentially trying to create the cause from effect, rather than what the study itself said, that cause led to effect.
Okay, right off the start, I have to make a few comments on faulty reporting, which is leading (and will lead) to bad conclusions.
1. The data was collected in 1970 and just recently analyzed. This is not a RECENT study by any stretch of the imagination, even though the article attempts to make exactly that claim in the second paragraph: “A new British study finds….” 1970 was over 40 years ago. The people studied back then are now reaching latter stages of adulthood, which means that their “habits” and the findings are relevant to a group of people who are now in their 50s and 60s, not children as the study claims to connect.
2. The “high” score for IQ was registered as between 107 and 158. Not really that high when it comes to what people refer to as “high” IQ scores.
3. IQ has never been an acceptable gauge of someone’s actual intelligence. There’s a reason that IQ scores are rarely used anywhere other than in comparison studies in which people try to use them to inflate their attributes. People generally don’t take IQ scores to begin with, and those who do often take them numerous times to try to “game” the system. Other people learn logic skills that help them “beat” the IQ test, and mostly, the scores are considered fringe on the levels of acceptable science.
4. The study makes inferences that may or may not be contributing factors. While the only claim the study makes is that people with higher IQs report higher levels of using drugs in later years, there is no actual connection to drug use AT THE TIME of the IQ test, so there’s no way to know how much more education a person may or may not have had since having an IQ test. Socioeconomic factors were mentioned, but weren’t really discussed at length.
5. The study (and the author of the article) make a lot of guesses as part of the study, indicating that maybe people were “bored”, and thus turned to drugs because their higher IQ put them in a bored state of mind in comparison to other people with lower IQs who might not be as bored because, I guess, they don’t have as much to think about with their lower IQs. I mean, that’s the inference of that statement, but I’m just guessing based on the lack of information contained in the article itself. Seriously, anyone can do that kind of logical exercise, even people with low IQs like me.
The worst part of this study is that the way it is reported means a whole bunch of people are now going to be “armed” with faulty logic as trivial information they store away. When someone is at a party and someone offers him or her cocaine, rather than think, “no, that stuff might be dangerous”, in the back of someone’s mind is going to be the thought, “well, I did read this one study once that told me that people who take drugs are more likely to have higher IQs, so it might actually be to my benefit.”
It doesn’t take a genius to see that one coming.
