One out of every 20 time series show spurious correlation at the 95% significance level ( and even more if you let me choose how to adjust, smooth, truncate, or detrend the data).
Causal mechanisms leading to successful prediction are the hallmark of science. Correlations are good motivators to look for causal explanation but correlation should not be confused for causality. Who would like to wager that the correlation that Eugene comes up with will not depend on detrending, smoothing, truncation of data, or some other manipulation to acheive it's purported statistical significance?
