The Halo Effect in Productivity:

Hi friend,

I've been thinking about something uncomfortable lately: how easily we mistake competence in one area for expertise in everything.

You know the pattern. A fitness YouTuber with 2 million subscribers starts giving career advice. A successful entrepreneur begins teaching you about relationships. A productivity expert pivots to mental health coaching.

And we listen. Because they've already proven themselves in one domain, we assume they must know what they're talking about everywhere else.

This is the halo effect in action, and it's costing knowledge workers like us time, energy, and focus on advice that might not actually apply to our work.

What Is the Halo Effect?

The halo effect is a cognitive bias where one positive trait influences how we perceive everything else about a person.

If someone is attractive, we assume they're trustworthy. If they're well-spoken, we think they're organized. If they've built a successful business, we believe they understand productivity, psychology, relationships, and maybe even quantum physics.

The problem? Expertise doesn't transfer automatically.

Why This Matters for Knowledge Workers

You and I work in documents, meetings, code, and emails. Our productivity challenges are fundamentally different from:

• An entrepreneur running a physical business

• A fitness influencer optimizing gym routines

• A lifestyle creator managing brand partnerships

Yet we consume their productivity advice as if it applies universally.

The result? We implement systems designed for completely different contexts, then wonder why they don't work.

Examples I've caught myself doing:

• Following morning routines designed for people with flexible schedules (when I have back-to-back meetings at 9 AM)

• Adopting "deep work" strategies from writers (when my work requires constant collaboration)

• Using time-blocking templates from entrepreneurs (who control their own calendars completely)

None of this advice is bad. It's just designed for different types of work.

How to Consume Productivity Advice Smarter

Here's my new filter:

Ask: "Does this person actually do the type of work I do?"

If you're a knowledge worker:

• Look for advice from other knowledge workers

• Prioritize people who work in similar contexts (remote, async, meeting-heavy, etc.)

• Value domain-specific expertise over general productivity gurus

Ask: "What are their actual qualifications for THIS specific advice?"

Being productive doesn't make someone a psychologist. Running a business doesn't make someone a relationship expert. Success in one area doesn't automatically translate to wisdom in another.

Ask: "Am I trusting this because of the halo effect?"

Before implementing advice, pause and ask: Am I listening to this person because of what they're saying, or because of who's saying it?

The Uncomfortable Truth

I recently watched Matt D'Avella's video on self-help gurus, and one line stuck with me: "We should be wary of how easily confidence can distort how we interpret a message."

The best productivity advice for knowledge workers often comes from... other knowledge workers. Not from entrepreneurs. Not from lifestyle creators. Not from people whose entire job is creating content about productivity.

From people doing the actual work.

What I'm Doing Differently

I'm being more selective about whose productivity advice I consume. I'm looking for:

• People who actually work in knowledge work roles

• Specific tactics over universal principles

• Evidence and experimentation over confidence and charisma

• Humility and "I don't know" over having all the answers

And when I share advice here, I try to be clear: I'm not a productivity expert. I'm a knowledge worker experimenting with what works for this type of work, sharing what I'm learning along the way.

That's it. No halos. Just one knowledge worker talking to another.

What about you? Have you ever implemented productivity advice from someone only to realize it was designed for a completely different type of work? Hit reply and let me know, I read every response.

P.S. If you found this helpful, the ideas come from Matt D'Avella's excellent video "The Problem with Self-Help Gurus". Worth a watch if you have 30 minutes.
