Unspecific goals don't work.

Psychologists¹ Locke and Latham proved it.

In 1975, the two researchers set up a real-world experiment at a logging company.

Drivers were only loading trucks to 60% capacity.

For the control, all staff members were given an unspecific goal:

  • Unspecific goal = “Do your best.”

Performance did not increase.

The researchers then asked staff what a hard but fair goal would be.

They said 94%.

That became their new specific goal.

  • Specific goal = “Load trucks to 94% capacity."

One month later, capacity averaged 70%. Two months in, it was 80%. And four months, nearly 94%.

And it stayed there.

Why?

Because specific goals give people something to aim at.

Unit Asking Read online Which of these articles encouraged Brits to donate more? It's the one on the right. Research by Christopher Hsee¹ found that donors gave nearly twice as much when first asked to consider the needs of a single person before being asked to donate to a larger cause. This “unit asking” strategy made contributions feel more reasonable and personal. And it explains this² rather bizarre study: The study looked at the success rate of donation requests on the...

Hyperbolic Discounting Read online One of these ads looks 108% better value. Can you guess which? In 2025, Shotton and Flicker¹ tested ads like this in their book. 282 consumers were shown Sierra Nevada Pale Ale priced at $18.99 for 12 bottles. Half were told this equated to $1.58 per bottle. Among those shown the per-bottle price, 28.6% said it was good or very good value (more than double the 13.7% who only saw the total price). Framing the cost at the per-unit level made the purchase feel...
