Complex problems require complex solutions. This is a common assumption of decision-makers in science and society today. The age of Big Data and Machine Learning provides ample complex solutions, but are they always better than us humans? Dr. Florian Artinger shows in a number of case studies, from sports to management, that people have developed simple but highly successful solutions. In dynamic and complex environments, where a calculation of all influencing variables is practically impossible, human decisions have shown to be frequently much better than complex algorithms. The talk shows how combining human and machine intelligence will eventually lead to better decision making.
