Thanks! I'm not completely sold on the lithium hypothesis, either. But I find their arguments for some kind of environmental contaminant compelling, especially for the ways in which they refute some of the other major hypotheses for the increase in body weights (e.g. food variety, processed food, etc) Note that the SMTM folks recently published an article responding to the TDS data referred to by "It's Probably Not L…
Someone would write like this if they don't know anything about instrumental analysis and are just guessing as a result.
As an example, they don't seem to even understand that wet and dry weights are substantivel different measures, and speak as though Magalhães et al. (1990) is measuring wet weight; it is measuring dry weight.
I'm supportive of autodidactic study and outsider research, but this is, frankly, a mess. They should unweight their priors considerably and bring in some chemists.
