ALL MY BOOKS 10+% OFF
thanks to @Gumroad Day

Gumroad is the platform on which I sell my eBooks. It's their 10th birthday. To celebrate, they decided to cancel all transaction fees for the day, and I decided to match & pass the savings to readers

(discount links in the thread👇)
First, my most-sold book: "Ergodicity, as simple as possible."

It's the best book to get an intuitive understanding of one of the most important concepts to take good decisions regarding your career, relationships, and life in general.

Discount link: gumroad.com/l/ergodicity/g…
A review:
"100 Truths" is my second-most-sold book.

I'll let the reviews speak. Discount link: gum.co/100truths/gumr…
"The Control Heuristic" is THE book to read to understand how the way our brain is wired influences our behavior.

I explain irrational behaviors, illusions, addictions.
Also, I describe methods to beat resistance to change.

Discount link: gum.co/heuristic/gumr…
Some reviews:
Next, my two books on management.

The first, "Best Practices For Operational Management", contains the Four Principles Of Operational Excellence and the Eight Best Practices to Implement them.

Discount link: gum.co/opexbook/gumro…
A review:
My second book on management is "Teams Are Adaptive Systems".

It has 12 actionable chapters, each presenting an action that managers can take today to create a work environment worth engaging with.

Discount link: gum.co/teams/gumroadd…
If you are a @RoamResearch user, you might be interested in reading the previous two books as a Roam Book.

Here it is (discount link): gum.co/roambook/gumro…
Finally, there's my "Antifragile Organizations" course. The April edition is already complete, but there are a few places available for the May one.

Discount link: gum.co/antifragileorg…
Again, all discount links are only valid for the 7th of April (#gumroadday).

So, make sure you get my books and courses while they are at a discount!

THE PYRAMID OF RISK

Bigger risks are infrequent; organizations that use them as indicators of problems will only react when it's too late.

Instead, by measuring the basis of the pyramid, organizations can spot problems before they become catastrophes.

Thread (1/N) Image
2/ In the 30s, a researcher by the name of Heinrich studied workplace incidents and noticed that for each death, there are many injuries.

And for each injury, many near misses.

And for each near miss, many unsafe behaviors.

Hence the pyramid shape. Image
4/ The pyramid of risk is one of the most important concepts that a manager must know.

Here is why.

THE DISTRIBUTED BRAIN

Why do we fall prey of illusions such as the one below?

The answer lies in how our brain is wired

(thread, 1/N)
2/ Let's look at a fragment of the previous image.

It looks coherent and could plausibly exist.
3/ Also the other two fragments, when examined one by one, look plausible.

THE HIVE MIND FALLACY

Principle: organizations are not influenced by incentives weighting on it; instead, their behavior is determined by the incentives weighting on the decision makers inside them.

This is because organizations have no agency; no hive mind.

Thread,
1/N
2/ Let me explain with a metaphor.

When we talk about a colony of bees, we often believe it has a collective will (the "hive mind").

However, it never takes decisions itself.
Instead, its bees take INDIVIDUAL decisions, whose result converges on a group behavior.
3/ The same applies to companies. How often do we read headlines such as "Apple decided to design a car"?

However, Apple doesn't have agency.
Its managers do.

The decision was the result of individual managers taking decisions based on their individual information & incentives.

MEGA-THREAD OF ALL THE TIMES VIRUS LABS "LOST" DANGEROUS PATHOGENS

1/ SARS is documented to have escaped virus labs multiple times; twice from the same one

2/ The Institut Pasteur lost 2349 vials of SARS and once transported vials on a regular plane breaking protocols

(thread)
(I will post all sources at the end of the thread)
3/ More than 100 US labs with bioterror pathogens had faced federal sanctions for safety violations…

…and regulators allowed them to keep conducting experiments while failing inspections, sometimes for years.
