Portfolio Builder

Split a giving budget across causes when you aren’t sure which moral framework is right, compare two ways of doing it, and see how much they agree.

Build a portfolio

1. How sure are you of each framework?

Your credence: how likely you think each way of judging good is to be right, or how much you want it to count.

Welfare What reduces the most suffering and adds the most wellbeing?

Rights and duties What do we owe each other, whatever the cost?

Justice What is unfair, and how do we fix it rather than soften it?

Care Who depends on me, and how do I show up for them?

Faith and tradition What does my tradition ask me to give, and to whom?

Future generations What protects the people who aren’t born yet?

All life What protects animals and the living world for their own sake?

Flourishing What helps people become who they could be?

2. Your budget

Each lens spends its share

Every framework gets a slice of the budget equal to your credence and spends it on its own priorities.

Best on average

Scores each cause by your credence-weighted priorities, then concentrates on the top five.

Why a portfolio

If you think welfare matters most but justice and future generations count too, your giving can reflect all three in proportion. The builder explores how to act under moral uncertainty, without assuming one framework must decide every gift.

The two methods

Each lens spends its share. Every framework gets a slice of your budget equal to your credence in it and spends that slice on its own top causes. This resembles a moral parliament, where each view gets seats in proportion to your confidence in it. It tends to spread money widely.

Best on average. Each cause gets a score: its priority under each framework, weighted by your credence. The money then goes to the five highest-scoring causes. This resembles maximizing expected choice-worthiness. It tends to concentrate money.

When the two disagree, your answer depends on the method as much as on your values. Nobody has settled which method is right. That is Open Problem 16, and the builder shows you where it bites.

Relief or sources

The slider shifts money toward causes whose work tends to sit deeper on the depth scale, or toward relief. Neither end is correct. The point is to choose your mix on purpose, which is the treatment for the Symptom Trap.

What it isn’t

The builder allocates across cause areas, not charities. To turn a portfolio into gifts, take it to One-Click Split. The framework priorities are editorial judgments, published in src/data/frameworks.json for anyone to challenge.
