My lede:

Only 38% of licensed drivers have joined their states’ organ donor registries, with many deterred by long-held misconceptions about how the transplant system works, according to poll results released in April.

The survey of 5,100 American adults, conducted on behalf of the organ-donation advocacy group Donate Life America, found that:

• 50% think that registering as organ donors means physicians will not try as hard to save their lives.
• 44% say there is a black market in the U.S. for organs or tissue.
• 26% believe that patients determined to be brain dead can recover from their injuries.
• 23% who are undecided about donation wrongly worry that age or health conditions would make them unacceptable donors.

The whole shebang.
