Analysis of Forecast Accuracy in the Political Media

Krugman, in a recent post, mentions a recent study comparing the accuracy of various pundits.

Conclusion:

Our findings seem to agree with Tetlock’s research. Some studies suggest that conservatives have more rigid ideologies (Jost et al., 2003) In other words, they would be considered “hedgehogs.” Similarly, lawyers are taught to argue one side with a single analytical method; they, too, would be “hedgehogs” under Tetlock’s model. While not all liberals are foxes and not all conservatives are hedgehogs, these trends may be informative in explaining why our results are as they are. It may be that conservatives are inherently disadvantaged as prognosticators due to their ideological “hedgehoginess.”

Perhaps most importantly, being a good prognosticator seems to be a product of choices, not birth. Anyone can be good; all they need to do is avoid law school and buy into liberalism as an overarching philosophy. There is no inferior ability associated with being born, say, black or female.

For Trump, ‘a War Every Day,’ Waged Increasingly Alone - Responses

#1 @Jim Cricket - I think there might have been a more direct or apropos moral to the story, at least as it relates to Trump, in that he goes around blaming everyone else, fires them, until his term ends - the bottom of the bowl - and there is only one person left, and everyone realizes that there is only one person to blame, Trump himself. https://www.nytimes.com/2018/12/22/us/politics/trump-two-years.html?comments#permid=29862349:29864948 #2 Some people have seen a method to the madness of Trump, but he has always been a blithering, destructive idiot, and artless, heartless, and ignorant man. The only real question is how can we stop him? Minor mention, many, myself included, have thought impeachment might be problematic, Trump replaced by Pence, but considering all the harm Trump has caused, Pence would never really be quite so bad. Bad, but not nearly so.

Review: Valuing Wall Street

Valuing Wall Street by Andrew Smithers My rating: 5 of 5 stars The material was simple enough to digest, and certainly believable. It also provided good insights on the real behavior of investors, i.e. most investors are not long-term investors and the perils of retiring during a down period. The book also provides a good benchmark for when to invest, although the fact that I rode the market up on its fallacious valuation has not harmed me, since I transferred my portfolio to bonds before the market started heading down.

Response: Paging Robert Burns by Krugman

Along these lines, from a recent release, and supportive of your post: "Previous portraits of Davos delegates as uprooted jetsetters or global networkers easily overlook their influence on society. Our findings reveal that the forum actively shifts the burden for the solution of problems from governments and corporations to individual consumers, with significant personal and societal costs," the authors conclude. The release from Eurekalert
