The tutorial then delves into various types of cognitive biases, such as anchoring and confirmation bias, and statistical biases like forecast bias. It also addresses bias in law enforcement, including racial profiling, and discusses bias in artificial intelligence, highlighting real-world examples like healthcare algorithms and credit card distribution. The video concludes with a summary and references.
