"Those well-known experts who had pulled off a big windfall by going against the tide and winning were, over the long term, the worst at forecasting."

That sounds understandable to me, and there is a research to prove it.

This article provides confirmation of the idea that has the world in its grip. Egalitarianism prevails. Especially at Harvard. I will have to read the article to see all its biases. But it was guaranteed to be published in the HBR.

Not having read the HBR article, I cannot comment on that particular study. But I would note that the nature of the forecast and time frame are important considerations. The news article did note that the study only looked at three years of data. If the forecast related to only quarterly trends the conclusion that it might have just been a fluke forecast could be valid. But say someone had predicted the financial collapse we saw in 2008 with valid reasoning but was off in timing. In that case his or her forecast would be wrong for part of the time but someone who acted on it might have had some years of underperformance but avoided the debacle that was to come. That forecaster might be someone to listen to in the future. But even being right once for the right reasons does not mean that the person will be correct all the time on such major calls or even that they will ever be right again. In the end, one should listen to the reasoning but make one's own decisions.
