| Comment | I've done a bit of research - a *bit* - on pollution and health and while it's obviously not good, it's often not half as convincing as headlines might make you think. It's massively confounded with a lot of stuff like deprivation, and a lot of studies just look at overall pollution, and overall rates, without controlling for confounders.
Tale of two studies: we had one that showed links between pollution and cognitive impairment were....pretty shaky actually. Really struggled to get it published anywhere. Someone else in the group did one on heart disease which showed significant results and folk were like 'that'll get published somewhere huge no bother'. |
