The Bias Tax

The Bias Tax Checklist

One page. Four moves. Fewer expensive mistakes.

The whole system on a single page

Your brain runs on instincts that were built for survival, not for money. Left unchecked, they quietly tax every financial decision you make — the panic sell, the hype buy, the “it’s already down 40%, it has to bounce” trap. The Bias Tax Checklist puts the four defensive moves on one page you can keep next to you and actually use.

What you get: A free, one-page PDF you can print, pin, or keep on your phone — designed to be read in 60 seconds before you click “buy” or “sell.”

1. Mute the noise

Cut the feeds and alerts that manufacture urgency you don’t need

2. Add friction

The 48-hour rule and the blank-slate question that kill impulse trades

3. Rules over feelings

A fill-in sell-rules template you write once, calm, and follow later

🧮

4. Automate, then zoom out

Set investing on autopilot and stop checking — less is more

The centrepiece is the blank-slate question — the one sentence that defuses anchoring, loss aversion, and FOMO at the same time:

“If I were seeing this completely fresh — no history, no price I paid, no crowd — would I buy it today, at today’s price?”

Ask it before any money decision and most of the bias just… falls away.
