Are Process Goals Really 15 Times More Effective?

Does Research Really Say Process Goals Work 15 Times Better?

No. A systematic review and meta-analysis reported a much larger pooled performance effect for process goals than for outcome goals in the sport studies it included. Dividing the two reported effect sizes does not establish that process goals are literally fifteen times more effective.

That correction matters because the supported result is useful without the multiplier.

Where the number came from

Williamson and colleagues' systematic review and meta-analysis screened 17,841 records and included 27 sport studies. The authors reported pooled performance effects of 1.36 for process goals, 0.44 for performance goals, and 0.09 for outcome goals.

Episode 115 divided 1.36 by 0.09. The result is a little more than 15, which became the "15x" headline.

    C --> D["But standardized effects are not a ratio scale"]
    D --> E["Supported conclusion: process goals had the largest pooled effect in these studies"]

The arithmetic is real. The multiplier interpretation is not.

Why the division does not work

The reported values are standardized effect estimates. They express a difference relative to variability in the outcome measurements. They are not quantities with a natural zero that can be read like dollars, miles, or units produced.

The Cochrane Handbook explains that a standardized mean difference is reported in standard-deviation units. Cochrane separately describes a ratio of means as the measure intended to express how many times larger one mean is than another.

A value of 1.36 therefore does not mean "1.36 units of effectiveness," and 0.09 does not mean "0.09 units of effectiveness." Their quotient is not a defensible performance multiplier.

The near-zero outcome estimate also makes the ratio unstable as a communication device. If the smaller estimate moved close to zero, the supposed multiplier could become enormous without representing an equally enormous real-world change.

What the paper does support

The review found the largest pooled performance effect for process goals in the included sport literature. Performance goals had a smaller pooled effect. Outcome goals had a negligible pooled effect.

That finding supports putting attention on the behaviors and strategies an athlete can execute rather than relying on a desired finish alone. It does not mean outcomes have no purpose. The destination can organize the training, while the process directs the next controllable action.

The evidence also remains bounded. The paper concerns sport studies. It does not directly establish the same effect in company building, sales, creative work, health, or every personal goal.

The corrected version

The accurate public statement is:

In a systematic review and meta-analysis of 27 sport studies, process goals had the largest pooled performance effect among the goal types analyzed. The reported effect sizes do not support a literal fifteen-times multiplier.

The publisher version contains the full methods, study selection, results, and limitations. [[Process Goals vs Performance Goals vs Outcome Goals]] explains how the three goal types can work together, and [[How to Turn an Outcome Goal Into a Weekly Process]] converts the corrected idea into a practical method.

Episode 100 is a related conversation about building a founder operating system around repeatable action.

Sources and method

The research result comes from Williamson and colleagues' goal-setting review. The interpretation boundary comes from the Cochrane Handbook's explanation of standardized mean differences and ratios of means. The original "15x" statement is preserved in [[E115 Full Transcript]] as part of the historical episode record.
