I'm not sure the conjunction fallacy should be of operational importance to the giving of predictions, unless there is betting involved. What should I do instead, simply state "Bitcoin will rise to $5,000."? That's completely uninteresting, and I fail to see how anyone could judge that prediction based on anything other than my credentials and their prejudices. Saying "Bitcoin will rise to $5,000 due to X." gives people a window into my thinking and lets them judge for themselves whether my assessment is likely.
You could say “Bitcoin will rise to $5,000 (for example, due to X).”
It's time to look back to see what was predicted a year ago and how successfully it was.
But even more, it's time for the fresh predictions for the following year, 2014.
