Then head on over to Lumosity. Oh, of course, they don't tell you that's what they're doing. They have 'brain exercises' for you. Those 50 years of research that prove that "brain exercises" don't ward off Alzheimer disease, nor in fact do they have any other measurable benefit? You won't be hearing about that either.
Lumosity's partners? How about all those insurance companies, which partner to feed Ingenix, the world's largest health information database? Ever thought about applying for health insurance, or long-term care insurance? Well, you're *dumb*, so it's gonna cost you more. Or, you're doing something on IQ testing that shows you're going to develop Alzheimer disease, or Parkinson disease; so it's going to cost you more - a lot more - if you can get insurance at all.
IQ scores are the some of the most sensitive information about a person that can be compiled. They predict health, lifespan, income, educational status, crime risk (victim or conviction), and nearly anything else you care to name. I think it's very evil to steal and sell this information under the guise of providing brain exercises.
