An employee gets feedback from their manager: ‘Great work.’ But a peer says ‘You could improve.’ Now they’re unsure about their actual performance. One opinion was clear; two opinions create doubt.
The Original Discovery
Attributed to Erich Segal, author of ‘Love Story’ (1970). It illustrates the paradox of conflicting information—having more sources doesn’t increase confidence, it decreases it.
How It Works in Real Life
The Segal’s Law isn’t a rare phenomenon—it’s everywhere once you start looking:
- A stock analyst says ‘Buy.’ Another says ‘Sell.’ You’re now less certain than before you read either analysis. Conflicting expert opinions reduce confidence.
- A doctor says you have condition A. A second opinion says condition B. You were more confident with one opinion (even if wrong) than uncertain with two conflicting ones.
- A website has 2 metrics for success: revenue is up 10%, but customer satisfaction is down 5%. Which metric matters more? Two conflicting signals = paralysis.
Why This Matters to You
Segal’s Law explains information paradoxes: more data doesn’t always mean better decisions. Sometimes less information is better than conflicting information. When seeking advice, be careful about getting too many conflicting opinions—it increases doubt without improving decisions. Choose a trusted source and commit, rather than consulting dozens and ending up more confused. In business, don’t track 50 metrics. Pick the 3-5 that matter and measure those. Conflicting metrics paralyze.
