Sunday morning logic puzzle (a trifle easier than before)

Three smart men were trying to find out who is the smartest of them all. Or was at least most logical and quickest thinker. To resolve that, they went to a woman who had the reputation of being the smartest of them all. She devised a quick problem for them. She blindfolded them and painted a dot on each of their foreheads.

She then told them “I have painted a dot on each of your foreheads. The dots are either white or black in color. I am going to soon open your blindfolds. You will be able to see other’s dots but not your own. I am then going to ask you to raise your hand if you see a white dot (on either of the two friend’s foreheads). Then I am going to ask you to guess the color of your own dot”.

Saying so, she opened their blindfolds.

“You may raise your hand now if you see a white dot”

All three men raised their hands.

The three men started pondering and soon one of them – who was indeed a little smarter than the others – said “I have a white dot on my forehead”.

Question: How did the man figure out what color he had?
