The owner,Ray Murphy told me the following about the Carlson test:
"The same thing happened with The Carlson experiment. No one involved in the experiment claimed
they COULD pick introverted from extroverted people - they only agreed to have a go and see if
they could, but even if they had succeeded, it would have done nothing for astrology because it
was not a claim of astrology anyway - it was just another "flavour of the month" thing that some
*thought was astrology.
