President Trump's Tragic Sunk Cost Fallacy
By David Henderson
In his recent speech in which he threw out his earlier idea of ending the war in Afghanistan, President Donald Trump stated:
First, our nation must seek an honorable and enduring outcome worthy of the tremendous sacrifices that have been made, especially the sacrifices of lives.
I think I sniff a sunk-cost fallacy here. He seems to be saying that the past sacrifices of lives mean that the U.S. government should not get out. But past sacrifices of lives do not, in themselves, mean that future sacrifices are justified.
