Maybe. But numbers don’t lie
This is only said by people who've never actually taken a class about statistics.
Numbers may not lie, but they also don't make assertions. People suck at interpreting data and that fact is constantly utilized to mislead people.
I'm not saying this to defend pitbulls, just that bite statistics don't really tell us anything about innate aggression in dog breeds. Just like FBI statistics don't tell us about innate criminality in ethnicity.
Those bite statistics don't make any attempt to rule out misleading variables. It could be that pitt bull bites are reported more often because of the extent of harm they cause. It could be that people who gravitate towards breeds who are thought to be more aggressive are wanting and are training for aggression.
Statistics is hard, and can generally be used to shape opinions on just about anything.
