Wow, and everyone said that all that math for a CS degree is useless, finally the time has come! /s

So, how come no one caught the error before publication? How come Gladwell did not even look up what an igon value is? Etc.

Everyone makes mistakes, but seemingly the more successful the author the more responsibility they should bear that their overall point is correct and useful. And Gladwell serially misses these marks. At least that's how I interpret these arguments.
