I would go as far to say that most ‘peoples brains’ dont remember new names well, unless there is a strong emotion tied to the meeting of a new person (hate, fear, infatuation, etc) then its easy to forget what someone said by the time you have made some introductory small talk and moved on to a conversation topic or had to break off the conversation and go elsewhere.
I find i either have to have somebody else say their name a lot for it to stick or i mentally break off from the conversation when i can get away with it and in mind find a way of remembering their name with a trick like associating it with a similar sounding word, or a famous actor with the same/similar name, etc.
