Or, maybe not enough like a pundit, since "models" are least useful when dynamics of low frequency events change.http://fivethirtyeight.com/features/how-i-acted-like-a-pundit-and-screwed-up-on-donald-trump/ …

Polls said Trump was popular, but Herman Cain was also popular. Difference was changed dynamics. Smart "pundits" caught that, models cannot.

I'm a firm believer in empirically-grounded analyses but the real art & science is knowing what kind of data supports what kind of argument.

We needed more smart, empirical pundits to make sense of 2016. Not horse-race coverage, through data models or "source close to" narratives.

For low frequency events like presidential elex, "models" are another version of conventional wisdom, condemned to miss changing dynamics.

Well, the result was 1-7. For soccer, that's a bit like an top NFL team playing a mediocre college team.

But my point is that for low frequency events, judging data and also whether past models hold is .. expertise.
