Use a little more logic

I have never been "anally probed", but I must take Susan Tracey to task ("Take me to your leading scholars", October 14). She describes people as "logically challenged" for saying "the universe is huge, therefore there must be aliens, therefore these stories are true". But she goes on to say: "They may score high on measures of creativity, or be prone to fantasy and intense visual imagery, but so do a lot of people who have never claimed to have had contact with aliens." These may be necessary but not sufficient conditions.
