Is advanced science required?
Some persons have dodged truth movement problems by exaggerating the amount of scientific expertise needed to ponder them. Even in relatively advanced truth movement products are problems (for the media and government) that are found via simple methods, e.g. just reading the official reports. Lets consider naming explicitly varied categories of problems according to how simple were the methods used to see them.
a) Simple review of official documents
b) Official contradictions
c) Other contradictions (pop media, external public documents)
d) Omissions in NIST
e) Questionable ("recasting") assumptions (NIST)
f) Speculative assumption cast as "finding" (NIST)
g) Multiple simultaneous assumptions required (for walk off)
h) Some science is simple
