Daniel Kahneman: Economist and Nobel Prize winner is dead. In his work he explained why people often do not behave rationally, contrary to assumptions.

In 2002, Kahneman received the Alfred Nobel Memorial Prize in Economics. He developed the underlying prospect theory with the scientist Amos Tversky, who died in 1996.. Kahneman's 2011 book “Thinking Fast, Thinking Slow,” written for the general public, became a bestseller. It describes two ways the brain works when thinking: the fast, unconscious, emotional and intuitive system 1 and the slower, more logical, conscious system 2.
