Some "researchers" painted some corn blue, and some red. They had TWO groups of TWO cultures of monkeys, so 4 in total. BOTH cultures got corn of both colors, but in one the blue corn was made to taste bad, and in the other the red was. They found that in all cases the monkeys decided that they hated the bad corn, and switched to the other corn. Once they switched, they fully ignored the other corn.
The "researchers" changed the corn so both tasted the same, and the monkeys kept with their habit.
The monkeys CHANGED preference when they saw new locals eating the other corn.
They seemed SHOCKED by that! GIVE ME A BREAK!
Anyway, one woman couldn't help but chime in. She said that ALL changed EXCEPT for one dominant male. She said he was probably so full of testosterone that he was just too stupid to see that the others(His SUBORDINATES, as far as he was concerned) ate the other. Never mind that he may not even notice the difference, or that the leaders generally LEAD and don't follow.
