I have noticed most of the housemates at various times relayng bits of conversation they've been involved in to other housemates and their memory of those conversations being inaccurate.

People generally don't remember with absolute accuracy, word for word, what has been said by themselves and others. We shortcut in memory, and we remember things according to what we think we've heard rather what we have actually heard. We muddy our memory of what's been said with how those things made us feel and with our own personal perception of events (for example Callum may well remember a conversation in which he feels that Dexter was overly aggressive without in anyway recognising his own responses as equally so). We also muddy past conversations with present ones and with what other people have said about them in the intervening time. It is absolutely possible that these are instances of outright deception, but it is also entirely possible that these are instances of inaccurate memory.

If our memories of conversations were absolutely accurate there would be no such game as Chinese Whispers.
