I have a group of clients that have been referred to me by their superior. They are victims of the' sunk-cost-fallacy' (google it if you don't know, you might still be able to help)) (the investment bias). What can I do to fix this? I have explained to them the rational fallacy here. I have put their situation in context and explained the analogy. What do I do now? I need them to change their decisions/beliefs from A to B where A is being unjustly supported by this fallacious (lol fellatio) thinking.
