I have never taken a lie detector ttest but have heard they can be outwitted. A guilty person can pass a lie detector test. How I do not know. So that can't be the way.
Yes -
The visual test - one can see by their actions that a person has no common sense. People who lack common sense cannot hide it. It “oozes” out of them.
The audio test - one can hear their foolish speech. For some reason, people who lack common sense don’t try to hide it. Rather they seem to enjoy advertising it … and quite loudly.
ANYONE can administer these tests. I know I do, and I'm sure you do as well. When I watch and/or listen to trump, I administer the test... and the conclusion is - no common sense.
I administered a test just the other day…
After much consideration, this county decided to cancel its yearly county fair due to the virus (the place gets very crowded). Even though it meant a loss of hundreds of thousands of dollars for the local community (as well as for local non-profit organizations), they figured it wasn’t safe for the community.
My conclusion – they have common sense.
However, a few people in the community disagree. They want the fair to go on as usual. They even held a protest march. Now these same people are trying to organize the fair on private property (as if any insurance company will allow it).
My conclusion - not only do they not have common sense, but they’re ensuring that common sense won’t accidently “wander by”.
