Overview

“Science is a way of thinking much more than it is a body of knowledge.” —Carl Sagan

Science has become a point of debate in some quarters. Whether it's about climate change, wearing masks, or the use of vaccines — terms about 'following the science' have become more common. 

So what does being a scientific thinker mean exactly? While we couldn't hope to pin it down completely, this Playbook will help you make a solid start on developing a Scientific Mindset and toolkit of models. 

This Playbook includes the following sections, select a heading to jump to that section.
OBSERVE & QUESTION
This involves being open to the environment and your observations, and asking questions to explore and engage with your world.
The Scientific Method
Of course, any talk of scientific thinking must begin with the Scientific Method. Such a foundational model for anyone who considers themselves as a critical and creative thinker. We'll be using this model to frame how we present you with the rest of the models in this list.
Occam's Razor
Use this powerful model to cut down on assumptions and look for the simplest, most logical solutions.
Curiosity Zone
Much of a scientific mindset is built on unashamed curiosity, from asking 'why' to remaining open to something new and disruptive even as you develop expertise. This model will help.
5 Whys
Building on curiosity, be sure to dig deeper and go beyond the surface to uncover root cause. Dive into this model for practical help and techniques.
Map vs Territory
As you develop your hypothesis, be humble in the knowledge that the Map is not the Territory, and that your theories are unlikely to capture the complexity of what's around you, even as it remains useful.
RESEARCH & HYPOTHESIS
Reviewing relevant information and studies, and developing a hypothesis — a view of what is happening and why, that can be tested moving forward.
Probabilistic Thinking
As a scientific thinker, you'd do well to stop binary thinking. Instead, embrace a Probabilistic view and way of seeing the world.
CRAAP Test
You can't trust everything you read. Use this checklist to challenge your data and information sources and maintain a skeptical mindset.
Confirmation Heuristic
We aren't just irrational, we are consistently rationalising. Awareness of this bias, and our tendency to seek out information that confirms our beliefs, is a requirement to challenge our hypotheses.
Correlation vs Causation
Sometimes your interpretation and yearning for neat patterns will take data to places it has no right being. Use this model as a check on that.
PREDICT, TEST & ANALYSE
Testing your hypothesis and actively trying to falsify it as you gain a greater understanding of reality and develop new hypothesis as a result.
Agile Methodology
Working in a team? Use Agile to test and learn through iterations.
BRINGING IT ALL TOGETHER
These models are inspired by and reflect the Scientific Method.
Split Testing & A/B Testing
You've got to test that hypothesis and an accepted way of doing that is by comparing a changed variable against a control group. Click through into this model's summary for more.
Lean Startup
lock

Launching a startup or product? Use this model which again is inspired from the Scientific Method to stay on track.
DIBB Framework
This framework, inspired by Shopify, supports you to build data-driven cultures of innovation, at scale.
Butterfly Effect & Chaos Theory
lock

Use this model as a reminder that small things can make disproportionate impacts in complex systems. Its a reminder of the limits of lab, or relatively closed experiments when faced with the complexity of reality.
OODA Loop
Born from a top fighter pilot, this model interprets the Scientific Method as a form of rapid decision making and action.
Entropy
lock

And finally, embrace the Second Law of Thermodynamics to understand the backdrop we face and the nature of energy.
