How the Too Hard Pile Decision Journal Works

The decision journal on Too Hard Pile is a written record of a call you are about to make — the decision itself, what you predict will happen, and how confident you are — that the site brings back to you weeks later so you can check whether you were right. It is the part of the platform that keeps score, and a free account includes 5 journal entries.

What you actually write down

The journal is not a diary of what happened. It is a record made before the outcome is known, which is what makes it useful. Based on the site's description, an entry captures:

• The call — the decision you are about to make, stated plainly.
• Your prediction — what you expect to happen as a result.
• Your confidence — how sure you are, so that later you can separate a good call from a lucky one.

The order matters. You commit first, then the outcome arrives on its own. That is the whole point: if you write the prediction after you know how it turned out, you learn nothing.

Why it comes back weeks later

Most people make a decision, live with the result, and never revisit the reasoning. The journal closes that loop by returning to the entry on a delay and asking whether your prediction held up.

This separates two things that are easy to confuse:

A good decision can produce a bad outcome, and a careless decision can get lucky. Because the journal recorded your confidence and reasoning before the result, you can tell which one you're looking at. That is the "honest bit" the site refers to — it is the only part that keeps score.

How it fits with the drills

The two features do different jobs:

• Drills (1,300 of them, across 13 mental models) train the thinking tools — inversion, incentives, second-order effects, base rates, and so on — by making you answer before anything is revealed.
• The journal tests whether those tools are actually improving your real-world calls.

Drills build the skill; the journal tells you whether the skill is working. Neither replaces the other.

What it costs to use

A free account includes 6 drills, 5 journal entries, and the whole Toolbox, with no card required and no time limit. The site lists a separate Pricing page, so if you want more than those limits, that is where the paid tiers would be described. The free tier is enough to run the full loop — write a call, wait, get asked about it — several times over.

A concrete example

Say you are deciding whether to leave your job. You open a journal entry and write:

• The call: I will resign by the end of next month.
• Prediction: I will have a signed offer within 8 weeks, and my savings will cover 6 months of expenses.
• Confidence: 70%.

Weeks later the entry resurfaces. If you got the offer in 5 weeks, your prediction held and your confidence was reasonable. If you are still searching at week 12, the journal shows you where your model of the situation was off — not just that things went badly, but which assumption failed. That is the feedback a plain outcome never gives you.

When this is worth doing

The journal is most useful for decisions that are slow to resolve and expensive to get wrong — the kind the site frames as "too hard": where to invest, whether to leave a job, when to walk away. If a decision resolves in a day, the delay adds little. If it plays out over months, the journal is the only way to compare what you believed with what happened.
