My mother had her IQ measured by a psychologist at 132.

She believes in flat earth. She does many stupid things routinely. Like, she once let the TV turned on in religious channel even when she wasn't at home so the house would be continually blessed by the preacher on it. And she can't understand *anything* you try to explain her, no matter how didactically you do it.

Would you feel the right to be sure the psychologist, for some reason, adulterated the result?
