Helicopters are inherently unstable at low speeds, yet there are civilian models.

That was true for a while, but not any more. Now Japanese and even Korean car makers have better quality (if you compare vehicles of similar price).

Customers making only the minimum payments, and especially customers who are occasionally delinquent are very risky. Those are some of the strongest independent variables in behavior credit scores. Credit card companies are not making much

There is a good reason why payday loan rate is so high: the loss rate is also high. Otherwise competition would drive the rates down, just like with mortgages or credit cards. This has nothing to do with morals, it's just economics.

I belive that. For example, Amazon is selling "DOT approved" H11 LED headlights with good reviews. One problem is that they blind oncoming drivers (I know because I bought them and tried). The other problem is that DOT does not ap

You can see at 0:44 here https://www.youtube.com/watch?v=pl4-cO6pO34 that a portion of the side airbag is in the upper part of the A pillar. Here's what under the cover: https://www.youtube.com/watch?v=

Passive safety. A-pillar might be so bulky because it contains curtain airbag and provides structural stability necessary for good crash rating.

Yet the same argument can be made for (any specific aspect of) intelligence.

by pps43 8y ago
I agree that long division measures some dimension of intelligence. But there are so many dimensions that knowing a coordinate in one dimension does not tell you much about coordinates in other dimensions. Taleb's point is that there i

IQ tests measure ability to correctly guess what test creators meant. Many of those questions have multiple correct answers, especially the more "complex" ones.

I gave examples elsewhere in this thread that illustrate why more time won't help. There is a large difference between solving the same type of problem, only larger, fast, and using abstractions at a higher level. Do you really think t

Typical lease is three years. In that timeframe there isn't a bunch of scheduled maintenance. You need to pass state inspection a couple of times, but apart from that there's normally nothing really to service yet. From the carfax

You also need to multiply the price of fixing a car under warranty by probability of the car breaking before that warranty expires. CarMax only makes money on the cars it sells, so as long as there is a decent chance the car will break aft

The problem is not whether the answer is binary. The problem is that the author of the test needs to have at least the same level of intelligence (and probably even higher) than what the test is measuring. Otherwise how can you tell if the

Asymmetric information. The buyer has no way of knowing whether the car was used gently, which results in market for lemons. CarMax has no incentive to fail a car at inspection. They'd rather sell it to you and if it breaks, fix it und

The point Taleb is making is that IQ works well in the lower half of the distribution, but not in the upper half. Which makes sense, considering that questions for IQ tests are created by people with close to average intelligence. Imagine t
