TLB #67 On choosing managers

Hello Shaker,

Me opening the subscriber count: 👁️👄👁️

5k+ subscribers… y’all really did that 🥹

To Anamaria, L&D Shakers, and every single one of you, this means more than I can put into words 💛

What started as a simple roundup has turned into something much more. A learning diary, a community space, and hopefully, something that gives you at least one idea you can take back to work each time.

This isn’t mine, it’s ours. I’m just putting together the incredible work so many of you are already doing.

So, truly, thank you. For reading, sharing, and being here. We don’t take this for granted 💫

I could write an entire post about Anamaria, but I’ll behave. 🤭 You’ve built something truly special here, and we’re lucky to be part of it! 💛

Got ideas to make the next 5k even better? I’m all ears 👀

Next stop, 10k? 😛🔥

— with gratitude,
Sejaal

Here’s what you’ll find in today’s Learning Brief:

• On choosing managers, how do you actually identify a good one?

• Upcoming community events and meetups happening across the world

• A juicy mix of practical resources you’ll want to bookmark 😍

• The latest updates from our community 💫

We’ve built entire systems to develop managers. But how confident are we in how we identify them?

If I look at most organisations (and honestly, even my own past assumptions), we tend to rely on signals like:

• confidence

• visibility

• willingness to step up

• high performing

And they feel… reasonable.

But then you come across research that makes you pause and go, wait, why haven’t we looked up from this lens?

The research, conducted by Achyuta Adhvaryu, Ben Weidmann, Sonia Bhalotra and their colleagues, set out to solve exactly this classic problem:

What makes someone a “good” manager? And, how do you separate a manager’s influence from the inherent talent of their team?

To do this, they used a Managerial Value-Added (MVA) approach in a controlled lab setting with over 1,000 participants.

Here’s what they did:

(This is what the experiment looked like in practice - multiple rounds, rotating managers across teams.)

And here’s where it gets really interesting:

(This part is key - the study compares self-selected managers with randomly assigned ones to isolate the real “manager effect.”)

By rotating managers across different groups, they could statistically isolate the “manager effect” - identifying individuals who consistently improved team performance, regardless of who they were managing.

And importantly, they didn’t stop there.

They validated these findings using a field study of retail store managers, showing that the same patterns held in real, high-stakes business environments.

A high-quality manager is roughly 2x more valuable than a high-quality individual contributor.

Not because they do more work, but because they increase everyone else’s productivity by about 25%.

Participants who self-nominated for leadership roles actually performed worse.

The pattern? Overconfidence, especially in their perceived social and leadership ability.

The strongest predictors were:

• fluid intelligence (problem-solving ability)

• economic decision-making (making good trade-offs)

What didn’t matter much:

• personality traits

• demographics

• even the desire to lead

The highest-impact managers weren’t necessarily the most “inspiring.”

They were the ones who:

• matched people to the right tasks

• monitored progress closely

• kept the system running smoothly

It’s less about how you show up, and more about how well the system works because of you.

This is where it gets interesting for us.

Because this isn’t just about managers, it’s about the systems we build to identify and develop them.

We often equate potential with:

• aspiration

• past performance

• visibility

This study suggests we need to look at:

— decision quality

— problem-solving under constraints

— ability to improve others’ output

You can’t assess management capability through intent alone.

What to build more of:

— simulations

— scenario-based assessments

— short-term leadership rotations

And now with AI, this gets even more scalable. Use AI to:

• simulate team scenarios

• create realistic decision environments

• give people repeated practice loops

One of the hardest things to detect in leadership selection?

The gap between confidence and actual decision quality

AI-enabled assessments can:

• track decision patterns across scenarios

• compare confidence vs accuracy

• identify who consistently improves outcomes

This helps move us away from:

“They seem like a leader” to “They consistently make systems work better”

We’ve spent years strengthening the interpersonal side of management:

• feedback

• communication

• empathy

And those matter.

But this research points to something equally critical, and often underdeveloped: the ability to delegate work, match people to tasks, make trade-offs, and allocate resources effectively

If the most eager candidates are not always the best ones…

Then our systems need to:

• reduce over-reliance on self-nomination

• create objective entry points into leadership pipelines

When one person can influence team productivity by ~25%…

This is no longer just a development conversation.

It’s a business strategy lever.

Maybe the question isn’t:

“Who looks ready to lead?”

But:

“Who consistently makes others more effective?”

And those two answers…
might not overlap as much as we think.

Now, I would like to know from you, if you think about the best manager you’ve worked with, what actually made them effective? Tell me in the comments!

The lineup is stacked. 🔥 There are a few selected sessions we think you’ll really like:

🔥 ThoughtLab: The Campfire Method — How to Help Groups Open Up and Connect Deeply
In this highly interactive ThoughtLab, Jan Keck introduces a different approach to help groups warm up naturally, like building a campfire, not breaking the ice.

🔥 ID Power Hour: The SME Who Controls Everything

In this interactive session, we dive into a real-world case where instructional design takes a back seat as SME control increases. Together, we’ll unpack the tension and think through what good looks like.

🔥 L&D Shakers Book Club: Storyworthy
This time, we’re diving into Storyworthy by Matthew Dicks, a practical guide to finding and telling stories that actually connect.

We’ll kick off with a short overview, then swap stories, reflect, and experiment with simple techniques together. Whether you’ve read the book or not, you’re very welcome to join.

…and many more 👀

We’ve also got local hub offline events happening in London, Munich, Amsterdam, and Dublin, so if you’ve been meaning to meet fellow Shakers in person, this is your sign. 🙌

[ 👀 Read ] The Autonomous Learning Ecosystem by Lori Niles-Hofmann

This is a must-read if you’re rethinking what L&D looks like beyond courses. Lori Niles-Hofmann challenges the idea that AI transformation is just faster content creation, and instead lays out a shift toward a more autonomous, system-driven learning ecosystem. It’s especially useful for understanding how L&D work is evolving upstream—and why clarity on the real business problem matters more than ever.

A very practical read if you’re already using AI in your workflow.

[ 🧰 Use ] Conflict Management Canvas by Fearless Culture
