When I tell you human intelligence is broken, try to understand that I am understating the problem. This is the kind of evidence that arises constantly:

“…I received some timely information this evening from my new brother-in-law, Carter. When he heard that I was monitoring the geese along the river, he told me that last year, at Henderson Lake here in town, guys from the city (city employees) were going to each of the nests and shaking the eggs so that the developing goslings inside would die. Apparently, they do this ‘so that there won’t be too many geese at the lake.'” — Ryan HeavyHead

I cannot help but want to go around and shake these guys until their brains shut off ‘so that there won’t be too many idiots reproducing in the gene pool anymore’.
