ELI5: Why is it that most airliners have the small wings behind and the big wings in front, and very few have the big wings behind and small wings infront? In other words, why is the Canard arrangement so rare?

With a "regular" tail, if the plane gets tilted so that the tail is really high or really low, the air pushing on the tail will push it back toward normal, level flight.

With a canard, if the plane tilts so that the canard is really high or low, the wind pushing on the canard will push it even farther up or down.

So a plane with a canard is harder to control.
