NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

AOC’s Green New Deal has not gone down well with her party’s union backers:

As in the UK, there is an increasing disconnect between left wing parties and their traditional working class supporters.

AOC, Corbyn and co seem to care more about their metropolitan ideas than the interests of their voters they are supposed to represent.

The Half-Life of Facts

I enjoyed this book and I believe it provides an important insight. It fits well with Thinking, fast and slow (Kahneman) The  author starts with a deliberately fuzzy/loose pragmatic definition of  “fact” and proceeds to explore the quantitative aspects of evolution (or temporal characteristics) of knowledge and information. He uses mathematical and statistical tools to explore patterns, suggesting common or universal mechanisms.

I learned a lot from this book. However, I found the repetition of the statement  underlying regularity not an argument.  I felt that the underlying potential mechanisms that lead to these regularities were tantalizingly suggested but not explored.

The seven pillars are:

  • aggregation
  • information
  • likelihood
  • intercomparison
  • regression
  • design
  • residual

Professor Stigler also hints at an emerging eighth pillar.

I particularly enjoyed this excerpt (quote from Alfred Marshall 1885):

the most reckless and treacherous of all theorists is he who professes to let facts and figures speak for themselves, who keeps in the background the part he has played, perhaps unconsciously, in selecting and grouping them and in suggesting the argument post hoc…
