In 2008 the brothers Brafman wrote “Sway: The Irresistible Pull of Irrational Behavior“. They tell the story of Ori Brafman being told, on his first day in his MBA course in Tel Aviv in the 1980s, that
“People aren”t rational.”
In my 1990s tertiary course into OHS Risk Management, we were still being referred to the 1965 book, “The Rational Manager“. Occupational health and safety (OHS) seems to still be based on an assumption of rationality in OHS management systems, decision-making and working yet it does not take too much exposure to the reality of work to understand that we must anticipate irrationality.
