The problem, in my view, is that the obstacles are so great anyhow that this type of research finds itself being penalised for reasons which, on the face of it, are ethical, but which actually are no such thing.
Minu meelest on probleem selles, et takistused on nagunii sedavõrd suured, et selle valdkonna teadust karistatakse põhjustel, mis tunduvad eetilised, kuid tegelikult seda ei ole.
