Homeopathy is one of the most enduring forms of snake oil available to consumers; it has been duping people since 1814. But the United States government only recently decided to clamp down on these bogus treatments, with a new policy from the Federal Trade Commission.
The FTC’s policy statement explains that the agency will now ask that the makers of homeopathic drugs present reliable scientific evidence for their health claims if they want to sell them to consumers on the US market.
Mustering that evidence is likely to be difficult given that homeopathy is a pseudoscience.
The main idea behind homeopathy is that an animal or plant extract that causes symptoms similar to the ones a person is suffering from can cure the symptoms. An example: Because onions make eyes tear and noses run, diluted onion extract is thought to cure cold and hay fever. So homeopathic remedies on the market are just extremely diluted versions of plant or animal extracts believed to bring relief to symptoms.
The trouble is that whenever researchers have looked at the homeopathic treatments, they find they do not actually contain traceable amounts of the original plant or animal material they were supposedly diluting.
The Myers-Briggs Type Indicator is probably the most widely used personality test in the world.
About 2 million people take it annually, at the behest of corporate HR departments, colleges, and even government agencies. The company that produces and markets the test makes around $20 million off it each year.
The only problem? The test is completely meaningless.
“There’s just no evidence behind it,” says Adam Grant, an organizational psychologist at the University of Pennsylvania who’s written about the shortcomings of the Myers-Briggs previously. “The characteristics measured by the test have almost no predictive power on how happy you’ll be in a situation, how you’ll perform at your job, or how happy you’ll be in your marriage.”
The test claims that based on 93 questions, it can group all the people of the world into 16 different discrete “types” — and in doing so, serve as “a powerful framework for building better relationships, driving positive change, harnessing innovation, and achieving excellence.” Most of the faithful think of it primarily as a tool for telling you your proper career choice.
But the test was developed in the 1940s based on the totally untested theories of Carl Jung and is now thoroughly disregarded by the psychology community. Even Jung warned that his personality “types” were just rough tendencies he’d observed, rather than strict classifications. Several analyses have shown the test is totally ineffective at predicting people’s success in various jobs, and that about half of the people who take it twice get different results each time.
