His data is irrefutable, but his conclusion based on his data absolutely is NOT irrefutable.
Because he lacks critical thinking skills, he doesn't seem to understand that correlation is not the same thing as causation.
Laughable - allow me to educate you.
Here is how it works. If a correlation doesn't exist, then there can be no causation. So, the fact that the data shows that there is no correlation between poor behavior and viewership means there is no causal factor. BUT if there were a correlation between the two, as there is between Kaepernick's actions and viewership, that is NOT NECESSARILY proof that one caused the other.
The data being discussed was of the first type - establishing that no correlation (and therefore no causation) existed. The logic and reasoning was flawless.
Now, it is true that we could propose a time series relationship or other multivariate relationship between multiple factors, and that the impact could be .........but I think you already have enough to reflect upon.
