Neuroscience shows that speed reading is bullshit

Despite the claims of speed reading apps, it turns out that you actually have to read the book if you want to learn from it.

Data is expensive

The metaphor is pretty clear: more data isn’t always better. In fact, in many cases, it’s a costly distraction or even a chance to get the important stuff wrong.

Here are the three principles:

First, don’t collect data unless it has a non-zero chance of changing your actions.

Second, before you seek to collect data, consider the costs of processing that data.

Third, acknowledge that data collected isn’t always accurate, and consider the costs of acting on data that’s incorrect.

Strip away all insignificant digits.

You’ve Been Hacked – The Psychology of Disinformation and How to Protect Yourself

Once seeded, viral misinformation exploits weaknesses in how the human mind determines what’s real.  Most people genuinely care about truth. I don’t mean that we tell the truth all of the time—though most of us mostly do—but that we very much want to know what is real. Reality can knock you flat if you don’t see it coming.

How not to be Stupid

Some years ago, I was working in the Netherlands for a client who shall remain nameless. I was in conversation with one of my team. How the conversation started or the detail of what it was about are lost to me. However, the topic was probably another act of incompetence by the client, or more likely, a partner on the project. We came up with the phrase “defining the cock-up blocker”. I was sufficiently taken with this that I jotted the words down in the “Whenever” category of my reminders app. There, the entry languished waiting for time and, more importantly, the inspiration to bring something to fruition.

Fast forward to a few days ago: an email appeared in my inbox from Farnam Street, How Not to Be Stupid. This was the title of a presentation by Adam Robinson to an investment conference.

I did a web search to find out more, but other than a presentation collection site that required a paid subscription for access to their archives, the only thing I could find was another brief interview on Something You Should Know.

Robinson’s premise is not that stupidity is not the opposite of intelligence. Stupidity, he defines as “overlooking or dismissing conspicuously crucial information”. This he apparently illustrated using a Gary Larson cartoon, but there are real-life examples.

Robinson identified seven factors that may cause us to make more stupid decisions than we might otherwise do.

1. Being outside one’s normal environment

2. Rushing—“the biggest trigger of all”

3. Being tired, physically or emotionally stressed

4. Being preoccupied or focusing on something intently

5. Suffering from information overload: talking while driving 

6. Being in the presence of a group of homogeneous individuals

7. Being in the presence of an authority: the junior pilot who doesn’t stand up to the senior pilot causing a collision on the runway. 

In any given situation not all factors need to be present, but they are additive: you’re in a new city, tired from the flight and rushing to make an appointment with your most important client.

So what can we do to reduce the chances of a cock-up?

“Mindfulness is the process of waking up to see what’s right in front of us.” (1)

1. Be aware that you are in a situation where one more of the seven factors might be operating.

2. Minimise the factors as much as you can.

3. Surround yourself by people who can give you honest feedback.

4. Once you are aware of the factors, don’t do anything that could have significant consequences.

The Principles of Critical Thought

My DayOne journal reminded me that I wrote this entry two years ago today. Given what’s happened in the world this year, it seemed appropriate to make it the first post for this year. I’m quite sure that this is not my original material, unfortunately, I carelessly omitted to note the source in my journal. So apologies to whoever it is I am ripping off and and Happy New Year to everyone.


Critical thinking is:

  • Questioning information rather than merely receiving it (trust but verify),
  • A constant skill applied to all knowledge and belief (not to be compartmentalised).
  • Not an exercise; but a tool for belief testing and filtering (defence against false beliefs).
  • Must be applied to yourself as well as others (self-question, self-test, self-critique).
  • Not radical scepticism (work out when information is enough to settle a conclusion).

Step 1: Check the facts (check multiple sources and evaluate their reliability).
Step 2: Check for biases and fallacies (your own and those of others).
Step 3: Consider alternative explanations of the evidence and test them.

  • Find the best defences of either side of a dispute and compare them.
  • Consider your existing background knowledge and endeavour to acquire more of it.
  • Rely on facts & evidence, not assumptions.
  • Update your beliefs when evidence goes against them.
  • Restate all your beliefs as probabilities; then justify those probabilities (or change them if you can’t).
