Mastermind was yet another shining example of how Maria can combine science and real-world application to help you improve your thinking in some way. Drawing upon stories from the famous detective Sherlock Holmes, Maria provides detailed instructions on how to improve your thinking. She touches on how to become a better observer and how to draw upon past experiences and elements in your “brain attic” (a collection of experiences and facts similar to Mozart’s bag of memories) to form better conclusions. The end goal is to ultimately make better decisions and avoid mental biases like the Availability Heuristic and the Confirmation Bias.
