I think we need to understand exactly what "peer review" is required for publication or publication certain places. Is it:

a) a grammar/spelling check

b) a gut check to make sure it "makes sense"

c) validation of the math/analysis

d) validation of the underlying experimental procedure used to collect the data

e) validation of the underlying selection criteria for inputs/candidates in the experiment

f) reproducibility of the experiment and results

g) something else?

h) all of the above

My impression is that "peer review" generally includes a & b and sometimes c & d.
