Perhaps, and studies such as these should have to withstand such questioning. But..... The problem as I see it isn't expiremntal design. The problem is larger scientific "design." To learn something useful with a sufficiently nuances understanding would take a lot of studies. Replication, redesign, boundary testing of the hypothesis, re-theorizing, etc. Science is supposed to be a process. With this, it may be possible to arrive at usable knowledge about human psychology and why/how we behave badly. This smattering of disparate studies, even if they were well designed and executed.... It just doesn't lead anywhere. If expiremnts and studies were pieces in a larger scientific endeavour, I think both quality issues resilience to quality issues would improve naturally.
