Reason on a Spectrum

4–6 minutes

Reason is not an oracle of truth but a spectrum-bound tool, and when it is worshipped as absolute, it curdles into pathology. True rationality knows when to temper itself, when to equivocate, and when a kind lie is wiser than a cold fact.

Reason and rationality are the household gods of modernity. We light incense to them daily: follow the science, be reasonable, act rationally. But before we genuflect, it’s worth asking what exactly we mean. By reason, I mean the faculty of inference – spotting contradictions, tracing causes. By rationality, I mean the practice of applying that faculty toward some end. That’s all. Nothing mystical.

The trouble starts when these concepts are treated as absolutes. They aren’t. They vary in intensity and application. A person’s reasoning operates on a spectrum with something like frequency and amplitude. Some minds hum at low frequency – broad strokes, contradictions smoothed over by intuition. Others burn hot at high frequency and amplitude – rapid logical leaps, obsessive consistency, the inability to let a premise go. And while some reason flows like a continuous wave – steady, consistent, predictable – other forms fire more like particles: synaptic sparks that don’t always connect, logic arriving in bursts or stutters rather than as a smooth line.

Push too far and what we sanctify as ‘reason’ bleeds into what psychiatry pathologises as autism or schizophrenia. Meanwhile, ‘normal’ cognition always includes an emotional ballast. Strip it out and the result looks alien, even monstrous. Freud’s quip about psychopathy – that the psychopath differs from the rest of us in degree, not kind – applies just as well to reason. Rationality is simply the socially acceptable blend of logic and affect. Deviate, and you’re declared broken.

Camus gave us a parable in The Stranger. Meursault observes his world with ruthless clarity, but no emotional resonance. He doesn’t weep at his mother’s funeral, and society condemns him less for murder than for failing to perform grief. His ‘pure’ reason reads as inhuman.

Here’s the paradox: if rationality means adapting effectively to one’s environment, then pure rationality demands knowing when to suspend itself. A person who insists on logic at every turn is not rational but maladapted. The rational actor lies, flatters, nods at the boss’s bad joke, comforts the friend who doesn’t want statistics but solace. Rationality that cannot bend collapses into pathology.

This is why the infamous ‘Do these jeans make me look fat?’ question is such a perfect test. The ‘true’ answer, if you are reasoning narrowly, may be ‘yes’. But true rationality recognises the context, the stakes, the human need beneath the words. The rational response is not the cold fact but the kind equivocation. Rationality that cannot lie is no rationality at all.

Here’s the paradox: if rationality means adapting effectively to one’s environment, then pure rationality demands knowing when to suspend itself. A person who insists on logic at every turn is not rational but maladapted. The rational actor lies, flatters, nods at the boss’s bad joke, comforts the friend who doesn’t want statistics but solace. Rationality that cannot bend collapses into pathology.

Consider the social rituals we all know. A partner says, ‘I like that house’, and the rationally over-tuned response is to evaluate the house. The actual cue is in the like, not the house. The answer isn’t that you dislike the house, but rather what you can appreciate about it. Miss that, and you miss the point. Or take the dinner table: when my son was seven, a well-meaning host – very Martha Stewart – asked him how he enjoyed his meal. He replied, with perfect candour, ‘I’ve had better’. From a logical standpoint, faultless. From a rational standpoint – if rationality includes social adaptation – disastrous. The question was never about the food. It was a cue for appreciation, for harmony. He gave fact when what was asked for was affiliation.

So yes, I attack reason and rationality – not because they don’t exist, but because they are misapplied, reified, and worshipped as neutral arbiters of truth. They are not. They are tools with a range, and outside that range, they fail catastrophically. To speak of ‘reason’ as if it were an unqualified good is like praising fire without mentioning its talent for arson.


After I wrote this, I realised I forgot to mention Kant.

Even Kant, patron saint of rational duty, insisted you must never lie, not even a white lie, not even to a murderer asking where your friend is hiding. For him, truth-telling was categorical, binding, immune to circumstance. But this is reason gone rigid, unable to flex with human reality. It shows how worship of Reason leads not to morality but to monstrosity. A rationality that cannot bend is no rationality at all.

Blinded by Bias: The Irony of Greed and Self-Perception

Greed is a vice we readily recognise in others but often overlook in ourselves. This selective perception was strikingly evident during a recent conversation I had with a man who was quick to condemn another’s greed while remaining oblivious to his own similar tendencies. I told him about the escalating greed of certain companies who profit greatly from selling their printer inks and toner brands. I’ll spare you this history. This encounter underscores the powerful influence of fundamental attribution bias on our judgments and self-awareness.

Exploring Greed

Greed can be defined as an intense and selfish desire for something, especially wealth, power, or food. Psychologically, it is considered a natural human impulse that, when unchecked, can lead to unethical behaviour and strained relationships. Societally, greed is often condemned, yet it persists across cultures and histories.

We tend to label others as greedy when their actions negatively impact us or violate social norms. However, when we aggressively pursue our interests, we might frame it as ambition or resourcefulness. This dichotomy reveals a discrepancy in how we perceive greed in ourselves versus others.

Understanding Fundamental Attribution Bias

Fundamental attribution bias, or fundamental attribution error, is the tendency to attribute others’ actions to their character while attributing our own actions to external circumstances. This cognitive bias allows us to excuse our behaviour while holding others fully accountable for theirs.

For example, if someone cuts us off in traffic, we might think they’re reckless or inconsiderate. But if we cut someone off, we might justify it by claiming we were late or didn’t see them. This bias preserves our self-image but distorts our understanding of others.

The Conversation

Our conversation was centred on an HP printer that has shown a ‘low ink – please replace’ message since the cartridge was first installed. I recounted the history of the ink and toner industry. HP had a monopoly on ink for their products, a situation that earned them substantial marginal profits. Upstarts entered the marketplace. This started an escalating arms war. HP spent R&D dollars trying to defend their profit margins with nil benefit to the consumers of their product. In fact, it kept costs artificially higher. Competitors who wanted a slice of those fat margins found ways around these interventions. Eventually, HP installed chips on their toner cartridges. Unfortunately, they have a bug – or is it a feature? If you install a cartridge and remove it, it assumes you’re up to something shady, so it spawns this false alert. Some people believe this out of hand, so HP benefits twice.

If this bloke had worked for HP and had been responsible for revenue acquisition and protection, he would have swooned over the opportunity. Have no doubt. At arm’s length, he recognised this as sleazy, unethical business practices.

This conversation revealed how easily we can fall into the trap of judging others without reflecting on our own behaviour. His indignation seemed justified to him, yet he remained unaware of how his actions mirrored those he criticised.

Biblical Reference and Moral Implications

This situation brings to mind the biblical passage from Matthew 7:3-5:

“Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? … You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.”

The verse poignantly captures the human tendency to overlook our flaws while magnifying those of others. It calls for introspection and humility, urging us to address our shortcomings before passing judgment.

The Asymmetry of Self-Perception

Several psychological factors contribute to this asymmetry:

  • Self-Serving Bias: We attribute our successes to internal factors and our failures to external ones.
  • Cognitive Dissonance: Conflicting beliefs about ourselves and our actions create discomfort, leading us to rationalize or ignore discrepancies.
  • Social Comparison: We often compare ourselves favourably against others to boost self-esteem.

This skewed self-perception can hinder personal growth and damage relationships, as it prevents honest self-assessment and accountability.

Overcoming the Bias

Awareness is the first step toward mitigating fundamental attribution bias. Here are some strategies:

  1. Mindful Reflection: Regularly assess your actions and motivations. Ask yourself if you’re holding others to a standard you’re not meeting. Riffing from ancient moral dictates, just ask yourself if this is how you would want to be treated. Adopt Kant’s moral imperative framework.
  2. Seek Feedback: Encourage honest input from trusted friends or colleagues about your behaviour.
  3. Empathy Development: Practice seeing situations from others’ perspectives to understand their actions more fully.
  4. Challenge Assumptions: Before making judgments, consider external factors that might influence someone’s behaviour.

By actively recognising and adjusting for our biases, we can develop more balanced perceptions of ourselves and others.

Conclusion

The irony of condemning in others what we excuse in ourselves is a common human pitfall rooted in fundamental attribution bias. The adage, ‘Know thyself’ might come into view here. We can overcome these biases by striving for self-awareness and empathy, leading to more authentic relationships and personal integrity.
