The behavioural biases discussed in Daniel Kahneman's 2011 classic Thinking Fast and Slow are central to Market Thinking and our efforts to not only understand the biases in other investors, but to control them in ourselves, We have now created a system that allows us to reduce our own unforced errors, while recognising them in others in order to understand better 'the narrative'. These tools are now being used in a newly launched UCITS fund bringing together Market Thinking and highly regarded alternatives manager Toscafund.
