1. The emotional part is an ironic twist because his use of stats are supposedly devoid of emotion.... just saying
2. This is the problem with a lot of staticians, they get arrogant about their results implying they show cause and effect, when in fact stats show neither. They only show that when one or multiple factor(s) is/are present another factor tends to change in corresponding or opposite direction in a predictable manner. Stats are always limited by the type of info gathered, the amount of it (sample size) and ability to quantify a certain skill set, always an issue when figuring out a human activity.
