- Too Much Information
The charge
We think in nominal money terms and ignore inflation, purchasing power, or real value. A number can look better even when it buys less.
How it operates
Nominal amounts are easy to compare; converting them into real terms takes deliberate mental work. That shortcut makes people treat price, wages, and returns as if the currency unit were fixed.
Logged incidents
- Incident 01
Employees celebrate a 4 percent raise during 6 percent inflation and feel richer despite losing purchasing power.
- Incident 02
A startup celebrates revenue growth that mostly came from price increases, even though real demand has softened.
- Incident 03
An investor compares nominal bond yields across years without adjusting for the different inflation environment.
What to watch for
Ask yourself: 'Am I looking at nominal dollars when real purchasing power is what matters?'
Recommended action
Default to inflation-adjusted dashboards and show every key figure in nominal and real terms. Real-versus-nominal reframing is the core fix.
