Depends on what we are doing with the data. A regression on it will optimise for global fit - thereby compromising predictions/inferences over the local imbalanced parts of the data.

Stats gaps of representativeness, selection bias etc., creep into these datasets. Media, policy making should consider them before forming opinions.

I wrote a book in Telugu where I addressed a few harmful beliefs (astrology, homeo, superstitions, biases) using basic stats concepts.

This blog of mine is one such attempt.

In a Gaussian distribution. An uninformative prior need not have any closed bounds.

So MLE would be identical to Bayesian estimate.

But give a closed bound (say mean height is uniformly distributed but within 100-200 cm) — Bayesian posterior estimates will consider this close bound — not MLE
