...or just form his own opinion based upon the available information. I, for one, am not telling anyone whether or not to wear a helmet but it is important for people "pressured" into wearing one that the matter isn't as clear cut as they or the pressurisers might imagine. Maybe that might be a liberating notion which frees the OP from something he doesn't want to wear. Maybe it allows him to reassure his family with the evidence. Or maybe helmets are "common sense" to him and any suggestion that they're not a good thing is ridiculous. Tediously rehashing the same helmet debate is unnecessary, but letting people know that there is a debate is not.
As above, there is nothing particularly special about the advice on helmets here. Ask a question about any purchase you're not sure about and if it is contentious you will get suggestions about what other people think you should buy, whether you need it at all, whether its safe etc. It could be a helmets, cycle capes, "safety levers", hi-viz, cleated shoes, etc.
