New learners frequently overestimate their competence early on — a well-known pattern often referred to as the Dunning-Kruger effect. A few basic facts create the illusion of a full picture, and it is only with more exposure that the true size of a subject becomes visible, often causing confidence to dip before it recovers.

Instructors who understand this curve can normalize the dip rather than let it discourage students. Framing a sudden drop in confidence as a sign of real progress — "you now see what you didn't see before" — helps learners push through the discouraging middle stretch instead of concluding they are simply bad at the subject.

Low-stakes checkpoints throughout a course, rather than one high-stakes final test, give students concrete evidence of the progress they are actually making, which counteracts the confidence dip with real data.
