People Who Prefer Black Coffee Are More Likely To Have Psychopathic Or Sadistic Traits, Study Finds (rd.com)
A new study conducted at the University of Innsbruck in Austria finds that people who drink their coffee black often has psychopathic or sadistic traits. The study surveyed more than 1,000 adults about their taste preferences with foods and drinks that are bitter. They also took four different personality tests that assessed traits like narcissism, psychopathy, sadism, and aggression. From a report: Researchers found a trend that suggested a correlation between preferences for black coffee, and other bitter tastes, and sadistic or psychopathic personality traits. They also found that people who enjoyed milky or sugary coffee, and other sweet flavors, generally tended to have more "agreeable" personality traits like sympathy, cooperation, and kindness. The closest correlation found in the study was between bitter foods, like radishes and tonic water, and "everyday sadism," or the enjoyment of inflicting moderate levels of pain on others. The researchers went further, suggesting that this association between bitter foods and psychopathic tendencies could "become chronic" and get worse with time.
This kind of BS discredits the entire scientific community.
I develop psychopathic and Sadistic Traits when I'm in line to order a coffee and the person(s) before me, ask for a double cream, piñata, spicey, cassonade, maple, cappuccino, with a gest of cittrus some cannelle and stuff like that
Ceci n'est pas une Signature !
If you're interviewing for a job and the interviewer offers you coffee, be sure to take cream and sugar even if you normally don't. Otherwise you might be signalling you're a psychopath or sadist. Of course, the reverse advice applies if you are applying for a police or correctional officer position.
If I can be modded down for being a troll, can I be modded up for being an orc, or a balrog?
This one fact completely explains pretty much the entire series of Star Trek Voyager.
I love black coffee, radishes, bitter-sweet chocolate, and gin and tonic. And I hope everyone involved in this study dies in a fire.
Well... real correlations with crappy R2 do mean that there's some connection between the two things.
First off, there's spurious correlations--where the most reasonable explanation for a statistically significant correlation (where the R2 is actually a very high value) is that it's just a really, really, really weird coincidence. This site lets you explore examples, and some have a very strong R^2 while also being quite unlikely to actually have a correlation--for example, the divorce rate in Maine correlates to the per capita consumption of margarine with an R^2 of 0.99...but there is no reasonable mechanism by which one could influence the other. That's actually part of why you're generally supposed to include some sort of theory when you're trying to show correlations, unless your goal is to create demonstrations of why it's wrong to assume that correlation even implies connection, no less causation.
Next, a R^2 of 0.02 is...fantastically low. The range is from 0 to 1, because it's basically a ratio. You can think of it very accurately as a measure of how well the line you just drew on the graph paper correlates to the data points--with 1 being the point at which it's perfect and 0 being where it has no relationship whatsoever.
Last? The usual cutoff for statistical significance in psych research is 0.05. Statistical significance is the point where you feel the correlation is strong enough that it isn't just cause by error--and one major cause of error is choosing a too-low threshold. And, well, 0.02 is less than half the normal threshold...
