lemon face
A derogatory term used to describe a person that is unaware of their ignorance on a certain topic despite insistence that they know what they are doing. The term came from a Cornell University paper called "Unskilled and Unaware of It" by Justin Kruger and David Dunning. The paper describes that generally the more intelligent tend to underestimate their abilities because they know what they don't know. On the opposite side those the are ignorant tend to not know what they are talking about yet feel that they do. In the paper an example is given of a man who smears lemon juice on his face because he thinks that it will keep cameras from seeing his face. After he robs a bank he is captured thanks to the bank camera footage. Even when shown the footage he could not comprehend how it didn't work. Hence the term lemon face.

I love it! Thanks! So
Great present for a retiring colleague with custom saying she's known for!

Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!

Perfect gift for my gf
Looks great! Came quick
Gave it to my nerd brother. He used it consume liquid

Love it

as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

This is SO cool. Morning coffee will always memorialize my new addition to the English lexicon.

Too inappropriate
Item came at appropriate time in good condition.
