Five Simple Strategies to Sharpen Your Critical Thinking



We're lucky to live in an age where the sum total of human knowledge is pretty much available at the click of a button. We've never had access to so much information. But not all of what's out there is quite what it seems. So here's a few strategies to navigate your way through and avoid falling out with people along the way.



1. Beware of Confirmation Bias

We all enjoy that sweet dopamine hit of feeling like we're right. In repeated experiments, psychologists have shown we're much more likely to accept something as evidence if it confirms what we already think we know. And much more likely to discount information if it contradicts our views. It's what's known as "confirmation bias".



It's one of the key "cognitive biases" that humans have, and it operates at an unconscious level – affecting our ability to process information. This is especially true for issues which are emotionally charged, or where our views are deeply held. But it can come into play at any time.  So don't rush to decide, and be actively prepared to change your mind.



2. Embrace Nuance and Complexity

So many of our discussions take place on social media platforms where algorithms reward our desire to see and hear our views confirmed. But in life, most situations are nuanced and complicated – acknowledging that can enrich the way that we view the world. For example, what colour is the sky? Well, the obvious answer is blue. But at sunrise or sunset, it can be red. On a cold misty morning, white or grey. At night, midnight blue or black.



But imagine for a moment the blue of the sky on a sunny day. Is it really blue? The colour blue has a short wavelength, meaning it scatters more than other colours – making it more visible to the human eye. So the sky looks blue to us humans, even though there's a whole spectrum of colours out there. Even something that seems totally self-evident can be more nuanced than you think.



3. Practise Intellectual Humility

One approach to, well, arguing, is to let go of the idea of being "right". Or at least seriously consider that you might actually be wrong. Putting yourself in the other person's shoes can lead to much more productive outcomes. Really try to understand where the other person is coming from. It's what's called "intellectual empathy". It can be challenging, but that's the point.



This can only work when both parties are engaging in good faith. Arguing just to waste somebody's time, known online as "sea lioning", not only makes you that guy or girl people avoid at parties, but we are intellectually, socially and politically worse-off for it.



4. Check Your Sources

It's more important than ever to know where your information is coming from. That sciency-looking graph about the dangers of feral Dalmatian puppies might look very convincing, until you dig a little deeper and find it was commissioned by fur-coat-coveting Disney villain, Cruella de Vil.



Be on the lookout for ulterior motives and vested interests. Becoming literate in the basics of scientific methodology, the use of data and the way it's presented are all weapons in your arsenal when it comes to critical thinking.



5. Avoid Fallacies

Whether engaging in online debates or arguing with Uncle Frank, it's very easy to lose our cool and resort to some less-than-sound tactics. One common tactic is what philosophers call, "The Straw Man" fallacy. Instead of engaging with the actual belief, you engage with a caricature. For example, if I said, "I prefer hamsters to gerbils," you might respond, "Oh, so you want to drown all gerbils?" A viewpoint that's much easier to take down.



Another fallacy is the "ad hominem fallacy", where you discount an argument because of your opinion of the person making it. This can lead to ad hominem attacks, which is basically Latin for name-calling. In that situation, it's fair to say that everybody loses.



Engaging in critical thinking isn't as fun as picking up a pitchfork, or feeling like you're fundamentally right. But in the long run, it leads to a more curious, educated and harmonious society, which ultimately is the biggest win of all.
