The Dunning-Kruger Effect
Dunning–Kruger effect
The Dunning–Kruger effect is a cognitive bias in which relatively unskilled persons suffer illusory superiority, mistakenly assessing their ability to be much higher than it really is. Dunning and Kruger attributed this bias to a metacognitive inability of the unskilled to recognize their own ineptitude and evaluate their own ability accurately. Their research also suggests corollaries: highly skilled individuals may underestimate their relative competence and may erroneously assume that tasks which are easy for them are also easy for others.[1]
The bias was first experimentally observed by David Dunning and Justin Kruger of Cornell University in 1999. They postulated that the effect is the result of internal illusion in the unskilled, and external misperception in the skilled: "The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others."[1]
Ok, I thought the person that showed it to me was joking.... You know, the old trick of posting something on Wikipedia then showing it to someone before it gets defrauded and yanked off. But I looked up the original research from Cornell, AND my friend showed me her copy from 2000. Amazing.....

What am I doing at 1:45 AM?
My neighbors sometimes complain that our roosters crow several times per night. We always wonder... why do they do that?
Finally, I am starting to formulate a theory. One that makes a little more sense that what people usually tell me. (which is, "Roosters can't tell what time it is; they're dumb." They've been doing this for many thousands of years; you'd think they'd get it by now!) I think that when I get up, to do my business, the roosters hear me, see the little bathroom light, and think, "Oh my gosh, it's morning already, the aunties are already getting up!" and start crowing. Only the young, inexperienced ones do this. And they quickly see their error. It's not getting light, and the air doesn't feel right for morning.
I usually check the time when I get up. Midnight or so. And 3 am. Those are my normal times. And the rooster(s) (sometimes one, sometimes more) is(are) crowing. We even jokingly called them our midnight roosters and our 3 o'clock roosters! I was thinking they woke me up, making me roll around and want to go to the bathroom. Now, with this new theory, I wake up (and get up), and then they wake up and crow. This is supported by this evening's incident. I couldn't sleep, and after trying for a few hours, I got up at 1:30 am (NOT a normal rooster crowing time by the original theory), and the roosters were crowing.
Well, it's quiet in the country. That's all I hear. Now the rooster has stopped and it is absolutely quiet. I guess I'll try to sleep again.
Shhhhh... don't wake the roosters!
