This experiment is a great example of cognitive bias . A human mind is full of biases which affects his decision making process and hence the outcome.
We experienced loss aversion bias during March 20 sell-off where investors dumped the equity to avoid further losses. Investors then tend to loose the focus of objective or goal for which investment was made and succumb to different biases .
Knowing the equity or for that matter any asset class & the return patterns by doing all data analysis may not translate into a positive investment outcome .You have to be aware of your own cognitive bias and its potential influence on your behaviour in order to achieve the financial outcome that you desire .
Hence knowing is not equal to understanding & desired outcome .
