We all think we're fair judges of the past. We read about ancient Rome or medieval Europe and believe we're seeing those societies clearly, evaluating them on their own terms. We're not. We're viewing them through a thick fog of assumptions we don't even know we have.
Here's the uncomfortable truth: you bring more baggage to history than a Victorian explorer brought to Africa. Your politics, your culture, your breakfast mood—they all shape what you see when you look backward. The good news? Once you learn to spot your own prejudices, you become a much sharper reader of history. Let's go hunting for your hidden biases.
Present-Colored Glasses: How current concerns unconsciously shape which historical questions we ask
Have you noticed how every generation discovers that history was really about whatever they're worried about right now? In the 1960s, historians suddenly found class conflict everywhere. In the 2020s, we're finding environmental degradation in every era. This isn't because previous historians were blind—it's because we ask questions that matter to us.
Think about what draws you to certain historical topics. If you're fascinated by women's roles in ancient Greece, that interest didn't emerge from nowhere. If you find yourself reading about economic inequality in the Industrial Revolution, your present concerns are whispering in your ear. This isn't necessarily bad—present concerns drive important research. But it becomes problematic when you assume past people shared your priorities.
Here's a test: When reading about a historical society, notice what angers or pleases you. That emotional reaction? It's your present values doing the judging. A medieval peasant wouldn't share your outrage about lack of social mobility—the concept barely existed for them. Your indignation is real, but it's yours, not theirs.
TakeawayThe questions you find interesting about history reveal more about your present concerns than about the past itself. Notice what draws your attention—that's where your contemporary bias lives.
Cultural Blinders: Why your background determines what historical evidence you notice or ignore
A fish doesn't notice water. Similarly, you don't notice the cultural assumptions you swim in every day. These assumptions act as powerful filters when you encounter historical evidence, highlighting some details while rendering others invisible.
Consider religion. If you grew up secular in a Western country, you might unconsciously dismiss religious motivations in history as mere window dressing for 'real' economic or political interests. Meanwhile, someone from a devout background might overemphasize religious factors. Neither is seeing clearly. A Crusader really did believe he was saving his soul—and he wanted land. Both were true simultaneously, in ways that feel contradictory to modern minds trained to separate sacred and secular.
Your cultural background also affects which sources you trust. Western readers tend to privilege written documents over oral traditions, not because writing is inherently more reliable—it isn't—but because that's how our culture transmits authority. An African historian might read the same archive and immediately notice what's missing: the voices that colonial administrators didn't bother recording.
TakeawayYour cultural background creates blind spots that feel like clear vision. The evidence you instinctively trust and the motivations that seem 'real' to you are shaped by where and when you grew up.
Assumption Hunting: Techniques for identifying and challenging your hidden historical prejudices
Now for the practical part: how do you catch yourself in the act of being biased? Start by noticing when historical people seem stupid or irrational. This is almost always a red flag. When you think 'how could they believe that?' you've likely hit a wall of assumptions. Past people weren't dumber than you—they operated with different knowledge, different values, and different logic.
Try this exercise: pick a historical belief you find absurd—say, the medieval theory of the four humors. Now argue for it as if you lived then. What evidence would support it? Bloodletting actually did make some feverish patients feel temporarily better. The theory had predictive power and therapeutic applications. It wasn't stupid; it was wrong in ways that required centuries of different evidence to discover.
Another technique: read historians from different backgrounds writing about the same events. A French historian and a German historian discussing Napoleon will produce remarkably different narratives from the same evidence. Neither is lying—they're genuinely seeing different things. When you notice these differences, you're glimpsing how background shapes interpretation. Apply that insight to yourself.
TakeawayWhen historical people seem irrational, you've found your own assumption. Steelman their beliefs from within their context, and read historians from different backgrounds to see how interpretation varies—then apply that skepticism to yourself.
Spotting your own biases doesn't mean achieving perfect objectivity—that's impossible. It means becoming aware of your particular angle of vision so you can compensate for it. The goal isn't to see history from nowhere, but to know where you're standing.
This self-awareness makes you a better reader of everyone's history, including the professionals. When a historian makes a claim, you can now ask: what present concerns might be shaping this question? What cultural background might highlight or hide certain evidence? You've become a bias detective. Use your powers wisely.
