never heard of this shit before The Athletic started pushing it in all their articles, but supposedly it can test cognitive reaction speeds

results are proprietary and sold to athletes and teams in several sports, but of course the founders (two neuroscientists) will release scores if it supports their test (ie Brock Purdy had a great score)

from The Athletic:

The exam lasts 40 to 45 minutes. It’s performed on a specially designed gaming laptop and response pad that can record reactions in two milliseconds. To put that in perspective, an eye blink lasts 100 to 150 milliseconds.

In one section of the exam, a series of diamonds flash on the screen for 16 milliseconds each. Every diamond is missing a point, and the test taker must determine — using left, right, up or down keys — which part is missing.

In another, the test seeks to find out how many objects an athlete can keep track of at the same time. In another, there are 22 figures on the screen and the athlete must locate a specific one as quickly as possible. The object might be a red triangle embedded in other shapes that are also red.
