Before the course is built

Setup asks about your situation first.

Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.

  1. Where does risk come up for you: money, health choices, work bets, or big life decisions?
  2. Do you tend to avoid risk entirely, or take it without weighing it?
  3. How comfortable are you with numbers like percentages and odds?

Right for now

If any of this sounds familiar, start here.

You avoid anything uncertain

Every risk feels like a potential catastrophe, so you take none and pay in missed chances.

You take risks on gut feel

It has worked so far, and you cannot say whether that was judgement or luck.

Probabilities do not mean much to you

A 20 percent chance and a 2 percent chance feel roughly the same in the moment.

Course arc

Where the course goes, in order.

Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.

01 / 06

What risk is

Probability and consequence together, and why fear tracks only one of them.

Reading odds

Making percentages, odds and frequencies mean something in the body, not just on paper.

Base rates first

Starting from what usually happens, and the mistake of treating your case as special.

Expected value, in plain terms

Weighing likelihood against size of outcome without formulas.

Irreversible versus recoverable

Why the kind of downside matters more than its probability.

Decisions and outcomes

Reviewing a risky choice fairly, whether it paid off or not.

What changes

What you will be able to do, and what you will stop believing.

You will be able to

Compare outcomes, not just odds

Weigh how likely something is against how much it would matter.

Use base rates

Start from what usually happens before adjusting for your case.

Separate decision from result

Know when a bad outcome was bad luck and when it was a bad call.

Ideas this course corrects

Risk is something to minimise

Risk is something to price. Avoiding all of it is itself a costly choice.

A bad outcome means it was a bad risk

Good bets lose. The question is whether the odds and stakes justified the choice.

Course questions

What to know before you start.

Is this a fixed course?

No. Cadence builds the course when you type the sentence and answer a few setup questions, so the lessons follow your situation. This page describes what a course built from this request covers. You see the whole path before Lesson 1.

Who is this course for?

A course on thinking about uncertainty in ordinary decisions. It covers comparing possible outcomes, using base rates, and separating a good decision from a good result, so risk stops feeling like a coin toss. It sits under Decision-making in the Work & ambitions part of the library.

Do I need any prior experience?

No. Setup asks what you already know and where you want to use it, and the course starts from there. Bring a real situation if you have one; the examples are built around it.

How long does it take?

Courses run 7 to 30 lessons of about 10 minutes, sized to what you asked for. One lesson a day is the intended pace, and you can go faster. Lessons can be read or played as audio.
