Abstract (emphasis mine):
The concept of a ‘Ballmer Peak’ was first proposed in 2007, postulating that there exists a very specific blood alcohol content which confers superhuman programming ability. More generally, there is a commonly held belief among software engineers that coding is easier and more productive after a few drinks. Using the industry standard for assessment of coding ability, we conducted a search for such a peak and more generally investigated the effect of different amounts of alcohol on performance. We conclusively refute the existence of a specific peak with large magnitude, but with p < 0.001 find that there was a significant positive effect to a low amount of alcohol - slightly less than two drinks - on programming ability.
I once worked in IT for an MSP that kept beer on tap in the office for this exact reason. Techs were encouraged to have a beer or two when stumped on an issue. It worked surprisingly well.
This did result in a few years of struggling with alcohol issues tho.
