Microeconomics
Marginal reasoning, at every step.
the shape of this subject
Micro is marginal reasoning done well. Brainback keeps you thinking at the margin — never the average.
Because microeconomics rewards the students who do the reps — and punishes the ones who outsource them.

Every microeconomics concept Brainback covers.
Add Microeconomics as a Learn subject and every problem in these areas routes to the Socratic tutor — attempt-first, hint-laddered, output-guarded.
What one turn in microeconomics actually looks like.
Attempt → correction → guiding question. No answer. Ever. Verbatim from a beta session.
Consumer's problem: MU_x/P_x = MU_y/P_y…
What does an extra unit cost? What does it earn?
no answer · one guiding question · your next move
How real attempts start. How Brainback nudges.
- Consumer's problem: MU_x/P_x = MU_y/P_y…
- What does an extra unit cost? What does it earn?
the anti-pattern
What microeconomics looks like when the AI does the thinking.
Answer machines make microeconomics look like a solved problem. It isn't. The exam room reveals whose reasoning was built and whose was rented.
- M1Reasoning from a single case to a general rule.
- M2Confusing correlation with cause.
- M3Ignoring base rates.
- M4Reading a result without checking the study design.
the recall card
What a spaced-repetition card looks like in microeconomics.
Every wrong attempt and low-scored explain-back becomes a card. SM-2 schedules them — the tricky ones come back tomorrow, the solid ones drift out to next week, then next month.
Recall the core concept in your own words. Then apply it to a fresh example under 2 minutes.
