This is just p-hacking. It's really sad that in 2018 researchers are still pumping out garbage like this. All of these toxo behavior studies have been very poor quality. For example, there's been a few studies purporting that folks infected with toxo have significantly higher rates of schizophrenia. However, this is false, because toxo rates differ by 2-3x between first-world countries but yet the schizophrenia rate is mostly consistent.
