Why do our tastes and preferences shift, remain inconsistent, or align with others? The answer lies in the interplay of evolution, memory, and context.

1. Taste is shaped by both context and experience

Our preferences are deeply linked to context and past experiences. Often, our individual choices are a reflection of associations we've made over time. For instance, though you might adore your blue sweater, a blue egg might seem unappetizing. Even within similar situations, preferences vary depending on external factors like setting or mood.

Additionally, humans frequently look to others to define their tastes. From an early age, we mimic what we see, influenced by social surroundings and trends. Preferences are also not hereditary; genes play a minimal role. Instead, our choices lean heavily on the pleasant experiences attached to items. A German study, for example, revealed that individuals raised on vanilla-flavored baby formula tended to prefer vanilla-infused ketchup later in life.

Color preferences offer an illustrative example of changing tastes. While infants are drawn to yellow-brownish tones because of their potential connection to survival instincts (e.g., a mother’s nipple), these preferences shift as negative associations with other yellow-brown items like vomit or feces arise.

Examples

• Adults raised on vanilla-flavored baby formula preferred vanilla-flavored ketchup.
• People tend to mimic peer preferences to fit in socially, as seen with popular fashion trends.
• Children’s preference for yellowish tones changes to more universally favored hues like blue as they age.

2. Evolution controls some food preferences, but culture has the final word

Our ancestors’ survival instincts still influence modern tastes. Sweet foods signal a higher calorie content, which was essential for survival in ancient times, while bitterness is often rejected due to its association with toxins. This basic wiring suggests why food preferences can feel so instinctive.

On top of biology, culture steps in to shape our palate further. Coffee and beer, both bitter, are cultural staples, yet no one is born enjoying these flavors. Over years of exposure without harm, we adapt, and even bitter profiles become palatable. Memory reinforces these adjustments—fond recollections of a delicious meal encourage returning to the same restaurant despite other, equally promising options.

Expectations also influence how we perceive taste. A visually appealing dessert, for instance, primes our brain to anticipate a delightful flavor, making us more likely to enjoy it. On the flip side, assumptions about airplane food often make it unappealing, regardless of its actual quality.

Examples

• Humans instinctively dislike bitter foods due to potential toxicity risks.
• Coffee and beer’s acceptance grew thanks to cultural exposure and safe experiences.
• A bakery cake viewed through a vivid display window is savored more due to heightened expectations.

3. Algorithms attempt to predict likes and dislikes

The explosion of media options has made selecting what to watch or consume more challenging. Algorithms, such as those used by Netflix or Spotify, analyze user behaviors to suggest content, attempting to streamline our choices. Netflix, for instance, assesses watched films and search patterns to propose tailored recommendations.

Ratings and user reviews, though, often distort results. Many users artificially inflate ratings for prestige films to impress others, even if they secretly prefer an action blockbuster. Online platforms like Yelp, relying on user feedback, can also be skewed; places flooded with positive reviews often draw negative backlash as dissatisfied patrons feel compelled to balance the praise.

In reality, these algorithms reveal patterns about our preferences but remain imperfect. They focus on what we consume rather than the exact reasons behind our choices. While helpful, these systems can never fully capture the fluid and context-driven nature of human taste.

Examples

• Netflix determines your preferences through your viewing and searching trends rather than explicit input.
• Prestige dramas often receive inflated ratings, unlike less "respectable" genres like comedies or horror films.
• Yelp reviews often show radical highs and lows due to contrasting user motivations.

4. Musical preferences hint at personality—but remain unpredictable

Music is deeply entwined with identity. It allows people to align with communities or carve out individuality. Fans of specific genres often cherish what the music culturally represents, whether it’s rebellion, freedom, or sophistication.

Interestingly, knowledge about a musician can alter our feelings toward their works. For example, Hitler’s affinity for composer Richard Wagner might discourage some from enjoying Wagner’s operas. Political tendencies also overlap with certain preferences—hip-hop fans in America tend to avoid voting Republican, while country music lovers often lean conservative.

Still, assumptions based on music can mislead. While some studies link specific behaviors to musical tastes (e.g., people leaving movies early are more likely to divorce), these generalizations are far from definitive. Musical enjoyment today reflects exposure and upbringing more than fixed traits.

Examples

• Punk music’s anti-establishment message attracts younger, rebellious audiences.
• Learning Wagner was admired by Hitler might change someone’s enjoyment of his music.
• Shared playlists showcase how suddenly diverse audiences can like similar tracks.

5. Personal preference is often illogical

When asked why we like things, we often don’t have a ready explanation. Our “likes” emerge faster than we can process the details behind them. For instance, visual preference for art happens within milliseconds, faster than conscious thought.

Beyond gut reactions, external opinions heavily influence our self-perceived tastes. Critics’ negative reviews can sow doubt in your response to a beloved painting. The art itself hasn’t changed—only the context around it has.

Finally, art is subjective, often shaped by context. For example, attendees at an art gallery might mistake ordinary objects like a fire extinguisher for “art” when guided by the exhibition setting.

Examples

• Most people cannot articulate concrete reasons for cueing up a favorite song.
• Reading a bad movie review changes audiences’ interpretations before seeing the film.
• What qualifies as “art” depends heavily on context—it’s rarely a universal judgment.

6. Tastes continually evolve

Tastes are far from permanent. Even “classics” we once adored in youth may later embarrass us. Such changes highlight projection bias—our tendency to believe current preferences will remain steady.

Selective memory builds this false consistency. We remember achievements and strong affinities while conveniently forgetting embarrassing bands, books, or fashion. Even outside events, like changing political climates or celebrity endorsements, can redirect trends, leaving us blind to what seemed inevitable before.

Other influences, like pop culture, deepen this fluidity. First Ladies’ names or hurricane names can, oddly enough, spike baby-naming trends. Yet predicting personal changes in taste, as these examples show, remains unpredictable.

Examples

• Impressionism moved from controversial to beloved within a few decades.
• Following Jacqueline Kennedy’s fame in 1961, “Jacqueline” spiked in popularity among newborns.
• Hurricane Katrina indirectly led to increased preference for “K” names like Kayla.

7. Experts are skilled, yet not immune to bias

Experts—trained judges in fields like wine tasting or art critique—bring experienced insights when assessing quality. Over time, their vast exposure sharpens their evaluations, leading to nuanced understandings of texture, balance, or composition.

Yet even experts aren’t unshakable. Context significantly impacts their opinions. For instance, Olympic judges rating gymnasts unconsciously score routines higher when following exceptional performances. National biases also creep in; knowing an athlete’s origin encourages comparative judgments favoring stereotypes.

While experts’ opinions offer value due to breadth of prior skill, they also highlight how no judgment can fully escape external influences.

Examples

• Wine specialists use thousands of tastings to inform subtle character analyses.
• Olympic judges show higher bias favoring athletes compared based on prior event quality.
• National context eerily reshapes sports rankings of identical participants.

Takeaways

1. When trying something new (e.g., food, music, or art), reflect on its cultural or associative factors rather than just first impressions.
2. Challenge outdated or stagnant preferences. Seek fresh inspiration by stepping outside familiar taste patterns and routines.
3. Limit over-reliance on algorithms. Embrace occasional platform-free experimentation with movies, music, or books to rediscover independent choices.
