The Advice Source Filter separates the quality of guidance from the confidence or popularity of the person delivering it. First, establish whether the adviser has achieved the relevant outcome in a comparable field. Then test recency: methods that worked decades ago may no longer fit today's technology, economy, or distribution channels. Narrow the claim to the person's genuine area of expertise, inspect commercial or emotional incentives, and compare the route they took with the route you are willing to take. Finally, pass the advice through your own judgement and seek independent evidence when the consequences are serious. The output is not automatic acceptance or rejection, but a reasoned decision about whether this particular advice fits this particular situation.
Origin
Developed in a Habits & Hustle solo discussion about the rise of social-media gurus and the need to distinguish authority from performance.
Core principles
- 01Relevant experience matters more than confident delivery
- 02Advice loses value when its original context expires
- 03A source's incentives can distort otherwise plausible guidance
- 04Good advice still has to fit the recipient's path and values
- 05High-stakes claims deserve stronger verification
How to run it
- 1
Verify relevant experience
Ask whether the source has actually done the thing they are advising you to do, in the same broad realm and at a meaningful level.
Pro tip Look for evidence of practice or outcomes, not just content about the topic.
Watch out Follower count and polished delivery do not prove practical competence.
- 2
Check the advice's shelf life
Establish when the source succeeded and whether the economic, technological, or professional conditions still resemble yours.
Pro tip Ask what has changed since their experience and which parts of the mechanism still transfer.
Watch out A real past success can still produce obsolete advice.
- 3
Bound the expertise
Identify the narrow domain in which the source has earned credibility. Treat claims far outside that domain as unverified rather than borrowing credibility from their strongest field.
Pro tip Prefer precise practitioners over people claiming expertise across many unrelated areas.
Watch out An authoritative voice can make breadth of claims look like breadth of expertise.
- 4
Inspect motivation
Ask what commercial, emotional, or personal outcome the adviser gets if you follow their recommendation.
Pro tip Trace social posts through their funnel to see whether the advice ends in a product pitch.
Watch out Incentives do not automatically invalidate advice, but hidden incentives reduce trust.
- 5
Test route and personal fit
Compare how the source achieved the outcome with your values, constraints, and desired path. Decide whether the recommendation works for your situation rather than merely sounding correct in general.
Pro tip Write down which assumptions about you the advice requires.
Watch out Even recent advice from a credible expert may be wrong for you.
- 6
Match verification to consequence
Use independent reviews, professional records, and other credible sources when bad advice could materially affect health, money, or safety.
Pro tip Increase the number and independence of checks as the downside grows.
Watch out Do not use a social-media profile as the sole credential for a high-stakes professional.
In the wild
A founder hears a celebrated entrepreneur recommend a retail-heavy launch. She confirms that his success came 25 years ago, before current online acquisition channels, and that he now sells a launch course. She keeps his principle of talking to customers but rejects the outdated channel plan and tests a small digital campaign instead.
→ The founder preserves a transferable principle without copying an obsolete playbook.
A patient finds a doctor with a large social following. Because the decision is high stakes, she checks current clinical practice, professional credentials, independent reviews, and whether the doctor's content schedule appears to substitute for practice. She then compares several qualified practitioners before booking.
→ The choice rests on relevant, current evidence rather than social popularity alone.
Common mistakes
Mistaking confidence for authority
Polished speech and memorable soundbites can create credibility without proving knowledge or practice.
Copying a valid but obsolete playbook
The adviser may have succeeded, but under conditions that no longer match the current decision.
Outsourcing your final judgement
A credible source cannot determine whether their method aligns with your values, constraints, or preferred route.
Is it for you?
Best for
People evaluating business, personal, professional, or health-related guidance from friends, experts, or online creators.
Not ideal for
Low-consequence preferences where experimentation is cheaper than researching the source.
From the transcript
“when you are asking people for advice, like make sure not only that they've done it before in the realm of what you're doing, but…”
“So you have to be able to assess everything that's being told to you and actually filter it through your own mind.”
“A lot of times people are giving you advice based on where they are.”
