If FDA officials err on the side of under-caution in approving an unsafe drug, they are attacked by the media and patient groups, and investigated by Congress. Their victims, sick and dead people, are highly visible. If FDA officials err on the side of over-caution, keeping a safe and effective drug off the market, who's to know? The victims are invisible. For example, neither the Americans who get sick or die from meningitis C this year, nor their loved ones, will know that their illness or death could have been prevented had it not been for errors by FDA officials. It's a no-brainer to figure out which error FDA officials prefer to make.
