Speciesism: the bias you never knew you had

You probably consider yourself a pretty fair person. You believe in equality, you call out discrimination when you see it, and you try to treat others with respect.

But there's a bias operating in your brain that you've likely never examined. It's called speciesism, and it influences everything from what you eat for breakfast to how you feel about wildlife documentaries.

The term sounds academic, but the concept is surprisingly simple. Speciesism is the assumption that some species matter more than others, not because of any logical reason, but simply because of the category they belong to.

It's the mental shortcut that makes us gasp when a dog gets hurt in a movie but feel nothing about the chicken on our plate. And once you start noticing it, you'll see it everywhere.

What speciesism actually means

Australian philosopher Peter Singer popularized the term back in 1975 in his book Animal Liberation.

He argued that discriminating against beings based solely on their species is morally similar to discriminating based on race or gender. The logic goes like this: if suffering matters, then it should matter regardless of who's experiencing it.

Think about it this way. We don't value human lives based on intelligence, appearance, or usefulness. A baby and a genius have equal moral worth.

So why do we draw such sharp lines between species? The uncomfortable answer is that we've inherited these categories without questioning them. They feel natural because they're familiar, not because they're justified.

How your brain plays favorites

Here's where behavioral science gets interesting. Researchers have found that our moral circle, the boundary of beings we consider worthy of ethical concern, is surprisingly flexible.

A study published in Personality and Individual Differences showed that people's willingness to extend moral consideration to animals varies based on factors like culture, upbringing, and even mood.

We're also wildly inconsistent. Dogs and cats get protected status in most Western minds, while pigs, who are demonstrably intelligent and social, get turned into bacon without a second thought.

This isn't rational. It's cultural programming running on autopilot. Your brain categorizes animals into "pet," "pest," and "food" before you even have a chance to think about it.

The invisible influence on daily life

Speciesism doesn't just affect what you eat. It shapes language, entertainment, and even law. We use phrases like "kill two birds with one stone" without flinching.

We laugh at cartoon violence against certain animals while crying over others. Legal systems assign property status to animals, meaning they have no rights of their own.

I started noticing this stuff everywhere after I went vegan eight years ago. The inconsistencies became impossible to ignore.

Why do we have animal cruelty laws that specifically exempt farm animals? Why is a fur coat controversial but leather shoes aren't? These contradictions only make sense when you understand the bias underneath them.

Why this matters beyond veganism

You might be thinking this is just a vegan talking point. But speciesism has implications that extend far beyond diet. Environmental policy, medical research ethics, and conservation efforts all bump up against this bias.

When we decide which species deserve protection and which can be exploited, we're making moral judgments based on arbitrary categories.

The good news is that awareness creates change. Research suggests that simply learning about speciesism can shift attitudes toward animals. You don't have to overhaul your entire worldview overnight. But recognizing the bias is the first step toward making more intentional choices.

Final thoughts

Nobody likes finding out they have a blind spot. It's uncomfortable to realize that some of your deepest assumptions might not hold up to scrutiny. But that discomfort is actually a good sign. It means you're thinking critically instead of just accepting inherited beliefs.

Speciesism isn't about guilt or perfection. It's about consistency. If you believe suffering matters, then it's worth asking whose suffering you've been ignoring and why.

You don't need to have all the answers. Just start asking better questions. The bias has been running in the background long enough. Maybe it's time to bring it into the light and see what you actually think about it.
