She was correct - as are you. Apparently, our minds are unless in dealing
with false information. If a fact is proven true - it is put in our "RAM".
The problem is we don't have much RAM, so there is no space for the false
data. 95% of responders who were "cold called" with this question get it wrong.
Not persuaded? Try this one - the question in each test is: "Can both
statements be true at the same time?"
Test 1
There is a pin and/or a bolt on the table, or else there is a bolt and a
nail on the table.
There is a bolt and a nail on the table
Test 2
There is a pin and/or a bolt on the table, or else there is a bolt and a
nail on the table.
There is a pin and a bolt on the table
Test 3
There is a pin and/or a bolt on the table, or else there is a bolt and a
nail on the table.
There is a nail but no bolt on the table
Test 4
There is a pin and/or a bolt on the table, or else there is a bolt and a
nail on the table.
There is no pin and no bolt on the table
