Sam Bankman-Fried’s fall hasn’t killed off ‘effective altruism’

Moya Lothian-McLean (Opinion, 25 November) appears to signal the death of “effective altruism” (EA) on the basis of the fall from grace of one of its most famous proponents, Sam Bankman-Fried. Just as Dr Andrew Wakefield’s discredited research into the MMR vaccine did not dishonour medical research in its entirety, nor should Bankman-Fried’s involvement in the collapse of the cryptocurency exchange FTX discredit EA. The aim of “doing good better” remains a laudable objective.Dr Guy A NorfolkBristol
