Overview
Ruth Chang’s insight is that hard choices are not hard because we lack information. They are hard because the options are ‘on a par’ — neither is clearly better, worse, or exactly equal. Comparing a stable job with a risky venture across a single scale is impossible because they are qualitatively different goods.
The model reframes the paralysis. When options are on a par, there is no pre-existing right answer waiting to be discovered by more analysis. Instead the choice is an occasion to commit — to put your agency behind one and become the kind of person who stands for it. The freedom is the point, not a bug.
When to use it
A decision feels paralysing because the options seem impossible to compare — career moves, big personal choices.
How to use it
Classify the options
Is one clearly better, clearly worse, exactly equal, or on a par (roughly comparable but qualitatively different)?
If clearly better/worse
It is not actually a hard choice — pick the better and move on.
If on a par
Accept that more analysis will not reveal a hidden winner; the scale does not exist.
Choose what you can stand behind
Ask which option you can commit to and defend as an expression of who you want to be.
Commit fully
Put your agency behind it. The commitment, not the comparison, resolves the choice.
Worked example
Someone agonises between a secure corporate role and founding a company, waiting for the spreadsheet to declare a winner. The model shows the two are on a par — different goods, not points on one line. The question changes from ‘which is better?’ to ‘which life do I want to author?’ They choose the venture, not because it scored higher, but because they can wholeheartedly stand behind it.
Common pitfalls
- Gathering ever more data to resolve a choice that data cannot resolve.
- Treating ‘on a par’ as ‘equal’ — equal options are interchangeable; on-a-par options are not.
- Delaying so long that circumstances choose for you.
Frequently asked questions
What does ‘on a par’ mean?
Roughly comparable in value but different in kind, so neither is better, worse, nor exactly equal.
Doesn’t this mean the choice is arbitrary?
No — it means the choice is yours to make an expression of your values, rather than a fact to uncover.
When is a choice not hard?
When one option is genuinely better on the terms you care about. Then just pick it.
