The NBA Draft happened last night, and sport geeks say it was the richest in terms of talent in years. Talent matters of course, but sometimes a player can just get hot at the right time and ride that streak all the way to victory. A coach would say the winning streak is all about confidence, but some scientists take a different tack on this - they’re looking at why we believe in the hot hand in sports or gambling. Because they say it’s all random; one outcome does NOT predict future outcomes. Andreas Wilke is an Assistant Professor of Psychology at Clarkson University.
