I am not giving her a pass for anything at all. I doubt anyone can prove or disprove her conclusions without all of the data. Someone said that she has released less than 1% of her data with her paper so far. We do not know if it's the best, worst, or just random, data from her study.
There is a lot written about Ketchum, but precious little from a factual basis about the data in her study. The data from her study is the key point as to whether her conclusions are valid. The rest (non study gossip and sniping) is pointless drivel.
Why are you giving her a fail for her conclusions? Do you have all of the data that the conclusions were based upon?
