Laboratory Bias
Lab bias is when scientists think they know everything, but the real world is like a slap in the face. Labs are fake places that make everything look easy, but real life is tough, like a test with no answers.
I did my lab on a perfect day, but in the real world, my cat knocked everything over.
The lab said the experiment would work, but outside, it rained and everything died.
My lab experiment was perfect, but in real life, my brother broke it.
