Give a fixed percentage, automatically, and decide where it goes on evidence rather than feeling. The case for it does not need theology: giving money to others reliably makes the giver happier, and that finding has survived a high-powered registered replication. What it will not do is return to you financially. Nothing suggests it does.
What is secular tithing?
Committing a set percentage of your income to giving — one, five, ten, whatever is sustainable — without the religious framework the word comes from. Fixed, automated, decided once.
The structural insight is worth keeping even if you discard everything else about the tradition. A percentage scales with your income, requires no decision when a request arrives, and survives months when you feel neither generous nor prosperous. It converts a recurring emotional negotiation into a setting.
Does giving actually make you happier?
Yes, and this is one of the better-evidenced claims on this site — which is not what I expected when I looked into it.
The original finding, Spending money on others promotes happiness (Science, 2008), combined a national survey, a longitudinal windfall study and a randomised experiment. Good design, small samples by modern standards.
The important part is what happened next. Under improved evidentiary standards, the central paradigms were re-run as high-powered registered replications — 712 participants in the first experiment alone, pre-registered so the analysis could not be adjusted afterwards. The prosocial spending effect held. That is a considerably stronger position than most findings in this literature occupy, and a great many popular psychology claims have failed exactly this test.
A later survey of 15,545 Americans found spending on others robustly related to happiness across age, gender and income groups — including among people who did not believe it would make them happier.
| Claim | Evidence strength |
|---|---|
| Spending on others increases the giver’s happiness | Strong — original experiments plus registered replication |
| The effect holds across demographic groups | Good — large survey |
| Fixed structure and predictability aid follow-through | Good — experimental |
| Giving returns to you financially | No evidence. No mechanism |
| Ten per cent is the correct figure | Tradition. Not derived from anything |
| Giving while in debt is advisable | Not supported. Usually the wrong order |
Why a percentage rather than deciding each time?
Because deciding each time means deciding while tired, and the decision is made under exactly the conditions that produce a no.
Fixed, repeated structure is what makes behaviour survive bad weeks — the same mechanism that makes ritual effective for anxiety is doing the work here. A standing order executes at the same rate in a month you feel generous and a month you do not.
It also removes something unpleasant that people rarely admit to: the quiet ledger. When giving is discretionary, you notice who asked, who thanked you, who did not. A percentage that leaves automatically has no audience and keeps no score, which is the same reason automating decent behaviour works better than intending it.
Where the money goes matters more than how much
This is the part most writing on giving skips, and it is where the actual leverage is.
The difference in impact between charities working on the same problem is not marginal — interventions vary by orders of magnitude in cost per unit of benefit. Choosing well plausibly matters more than doubling the amount. Independent evaluators exist for precisely this reason; GiveWell is the best known, and there are others.
None of that requires you to be cold about it. Give locally if that is what you value — but decide that deliberately, rather than by whichever appeal arrived most recently with the most affecting photograph. Emotional salience is not correlated with need, and the organisations best at producing it are frequently the ones with the largest marketing budgets.
How to set it up
- Clear high-interest debt first. Giving while paying twenty per cent on a card is a net loss to everyone. Sort the order.
- Pick a percentage you can hold for five years. One per cent sustained beats ten per cent abandoned in April. Start lower than feels impressive.
- Automate it on payday. Standing order, the day the money arrives. What you never see, you never negotiate with.
- Choose recipients once a year. One evening, using evidence of effectiveness. Not in response to appeals during the year.
- Split it if you want. A portion to effectiveness, a portion to what is near you. Both are legitimate; deciding the split in advance stops each request becoming a debate.
- Increase it with income, not with guilt. Raise the percentage when your income steps up. Do not raise it after a bad news cycle.
- Do not track returns. Not financial ones, and not gratitude. Expecting either converts the whole thing into a transaction that will disappoint you.
What running this taught me
I gave intermittently for years and thought of myself as reasonably generous, which turned out to be a claim about self-image rather than about behaviour.
The pattern was lumpy. A disaster appeal, a friend’s fundraiser, something that landed emotionally — then nothing for months, with the memory of the last one doing the work of an ongoing practice. When I eventually added it up over a year, the total was well under what I would have guessed, and heavily weighted toward whatever had been most vividly presented.
Switching to a standing order changed two things I did not anticipate. The obvious one is that the total went up substantially without ever feeling like more, because it was never a decision.
The less obvious one is that appeals stopped being uncomfortable. Previously every request carried a small negotiation and a residue of guilt whichever way it went. Now the answer is already settled — the giving happens on the first of the month — and I can read about something terrible without that particular knot. I did not expect the main benefit to be the absence of a feeling.
What the evidence doesn’t support
- That giving returns to you financially. No evidence, and the prosperity version of this doctrine specifically targets people who cannot afford it.
- That ten per cent is the right number. A traditional figure with no analytical basis. Choose what is sustainable.
- That giving to a spiritual teacher counts as charity. It is a purchase, and it should be evaluated as one — on the ordinary terms of any transaction.
- That anonymous giving is spiritually superior. It avoids some ego traps and forfeits accountability and the modelling effect. Neither is clearly better.
- That personal giving substitutes for structural change. It does not, and treating it as sufficient is a comfortable error — particularly given how little earnings track contribution, which is the problem with compensation-as-law.
Frequently asked questions
How much should I give?
Whatever you can sustain indefinitely after debt and essentials. The correct figure is the one still running in three years, not the one that sounds generous today.
Should I give if I am struggling financially?
Not at the expense of your own stability. Anyone teaching that giving from hardship produces return is selling the prosperity gospel, and it targets exactly the people least able to absorb it.
Does giving time count?
It is valuable and it is a different thing. If your skills are scarce and your time is not, money is often the more efficient contribution — and the happiness research here is specifically about spending money.
What if I do not feel good about it?
Fine, and not a problem to solve. The feeling is a documented side effect, not the purpose. The money arrives either way.
