- Too Much Information
The charge
People perceive the same evidence differently because expectations, motives, and prior beliefs shape what they notice and how they interpret it. The data may be shared; the meaning is not.
How it operates
Top-down processing filters ambiguous input through existing schemas. That means identical signals can produce different conclusions in different observers.
Logged incidents
- Incident 01
Growth and trust teams read the same funnel dip and reach opposite causal stories.
- Incident 02
Two interviewers hear the same answer and one calls it confidence while the other calls it arrogance.
- Incident 03
Executives view the same employee survey as either a culture warning or normal noise.
What to watch for
Ask yourself: 'Would someone with a different prior or incentive read this same evidence differently?'
Recommended action
Use blind review where possible, structured rubrics, and adversarial collaboration between people with different priors. Force interpretation before revealing identities or favored hypotheses.
Known associates
- Confirmation BiasWe seek, interpret, and remember information in ways that support what we already believe.
- Congruence BiasWe test whether our favored idea fits instead of trying to find out whether it fails.
- Choice-Supportive BiasWe remember the option we chose as better than it really was and the options we rejected as worse than they…
- Observer-Expectancy EffectAn observer's expectations can subtly change what they notice, record, or even elicit from others.
- Ostrich EffectWe avoid information that might be painful, threatening, or shame-inducing, especially when it could force…
- Subjective ValidationA statement feels accurate because it seems personally meaningful, even if it is vague or broadly applicable.
