This doesn’t make sense. The doctors were acting as though having more medication options somehow made medication a worse bet than surgery. But if 47 percent of doctors thought medication A was preferable to surgery, the mere existence of a second medication shouldn’t have tipped them toward surgery. What happened here is decision paralysis. More options, even good ones, can freeze us and make us retreat to the default plan, which in this case was a painful and invasive hip-replacement surgery. This behavior clearly is not rational, but it is human.
