| corner of time, and so ever more credulous of techo-
| spiritualists, mechanical mediums and silicon psychics.

    | tent of Madame Mystic Meg than a simple wish for foresight.
    | Machines that are eminently successful at foretelling might
    | only amplify that pathology (minus the incense, elegant
    | dress, mood lighting and arabesque panache).

  | 
  | Looking even one year ahead is good.

| choices (which I didn't notice) so 5/8 is actually good!

  | this is actually very encouraging.

  | Hedgehogs (who have a central big idea), but no-one was up to
  | much.

  | These aren't binary choices, so 5/8 doesn't seem too bad to me.

| Would love to see results presented with the uncertainty

  | It's definitely an odd emission since the original research

  | with a nice history graph.
  | 
  | As some wild speculation, I suspect that since the GJP only
  | employs a handful of Superforcasters, the initial confidence
  | intervals for these broad questions may be quite large. That's
  | to be expected when predicting a year in advance, but
  | publically admitting to have such a broad confidence interval
  | is probably not very good for marketing.
