Occam's razor says that if you have two competing ideas to explain the same phenomenon such as why was ISX in trouble, and one is complex, and one is simple, you should prefer the simpler one that simply requires a conspiracy between agencies that begin with A such as ASX, ATO, ASIC, AFR, AUSTRAC, A company called OM, A poster called JLO, A bunch of un-named Short Sellers, and A federal court judge.
