Signal vs. Noise

Cut through contradictions and find what the evidence actually says

Separates established evidence from marketing, ideology, and noise in any health, finance, productivity, or self-improvement topic. Three sections: what we actually know, what's noise and why, and what's genuinely debated. Ends with what to do and what to ignore.

Overview

SignalVsNoise is an evidence filter. Paste any contested topic — intermittent fasting, index funds, cold showers, productivity systems — and get a structured breakdown of what the evidence actually supports, what's noise and why, and what's legitimately still debated.

How to use it

1. Enter any health, finance, productivity, or lifestyle topic you've seen conflicting advice about
2. Review The Signal — claims with high confidence and the reason we know them
3. Review The Noise — marketing, cherry-picked studies, and methodology problems
4. Check Genuinely Debated — questions where reasonable experts still disagree
5. Use the Bottom Line to know exactly what to do and what to ignore

Example

Scenario: Is creatine actually worth taking for fitness?

What you do: Enter 'creatine supplementation for athletic performance'

Result: Signal: strong evidence for strength and power output, safe for most healthy adults. Noise: cognitive enhancement claims are preliminary, loading phase is marketing. Genuinely debated: optimal timing, long-term effects in older adults. Bottom line: if you lift, probably worth it. Skip loading protocols.

Tips

• Works best on topics where you've seen contradictory headlines or advice
• The 'sources of noise' section names who benefits from the misinformation
• The Genuinely Debated section is where intellectual honesty lives — don't skip it
• Use this before making any significant health, financial, or lifestyle decision
