<div dir="ltr"><div>I agree with Darin, the Harvard study is highly unlikely to be correct, GIGO and all that. Nothing that any "esteemed scientist" has said so far has had any acquaintance with the reality of this pandemic.</div><div><br></div><div>Models are highly malleable, by adjusting parameters within the model you can take any model and make it say whatever you wish. AI is subject to this as well. Since the parameters are hidden and it is often unclear to non-users what physical property the parameters control, this is an easy way to dupe the public. </div><div><br></div><div>Back when I was trying to understand published climate modelling tools, I found a paper on one of the models used by gov't (no, I don't remember the name) and it had *over 48 parameters*!! I remember my astonishment that the paper (which was publicly available, not an internal article) described the parameters as being able to be "adjusted to have model predictions that fit proposed data". The parameters were so numerous that they were named by alphabet letters - A, B, C...Z and then AA, BB, ... ZZ. </div><div><br></div><div>So - models are difficult and subject to meddling, and bigly caution is advised before trusting them IMHO.
