Why Do People Try New Things?

People try new things because unfamiliar experiences can reveal information about the world, available opportunities, and themselves that familiar routines cannot provide.

Familiarity is valuable because it reduces uncertainty. We know how a regular commute works, which meals we enjoy, how an established job operates, and what to expect from people and places we know well. Repeating successful choices saves time and protects us from having to relearn everything each time we act.

That advantage has a limit. Familiar choices continue giving us information about familiar options, but they tell us very little about alternatives we have never tested. Exploration becomes valuable when learning about those alternatives matters enough to justify some uncertainty.

Curiosity Makes Missing Information Matter

Curiosity often begins when we realize something important is missing from our understanding. A completely unfamiliar subject may not attract much attention because we do not yet know enough about it to recognize the unanswered questions.

The situation changes once we understand part of the story. A contradiction, surprising detail, or incomplete explanation creates a visible gap between what we know and what we want to know. Psychologist George Loewenstein's information-gap theory of curiosity describes this tension between existing knowledge and desired knowledge.

Mystery stories provide an obvious example. Readers are given enough information to recognize that something does not make sense, and the missing explanation becomes valuable because the surrounding context has made it meaningful.

Everyday curiosity works in much the same way. A colleague introduces an unfamiliar idea, a friend describes an experience we have never had, or new evidence challenges a belief we thought was settled. Exploration becomes a way of closing the gap.

Familiarity and Exploration Solve Different Problems

Familiar choices provide predictable rewards. If a restaurant consistently serves a meal you enjoy, returning there is a sensible decision because you already know the likely outcome.

Choosing a new restaurant gives up some of that certainty. The meal might be worse, but it could also introduce something you prefer to the familiar choice. Even a disappointing experience produces information that can improve future decisions.

This tension is often described as the exploration-exploitation tradeoff. Exploitation uses existing knowledge to obtain known rewards, while exploration accepts uncertainty to discover whether another option may be better.

Neither strategy is universally correct. Their value depends on what is already known, how much the environment is changing, the cost of experimenting, and the possible value of discovering a better alternative.

New Experiences Expand Future Choices

The value of exploration becomes clearer when the decision is more consequential than choosing a restaurant. Consider someone contemplating a different career.

Their current work provides known compensation, responsibilities, relationships, and routines. Another field may offer more satisfying work or stronger future opportunities, but those possibilities remain uncertain because the person has never experienced the work directly.

Exploration can reduce that uncertainty. A conversation with someone in the field, an introductory class, or a related project can provide evidence that thinking alone cannot produce.

The experience changes the person's future choice because the choice is now informed by more than assumptions about the unfamiliar option.

Surprise Can Correct Our Predictions

Some experiences become especially valuable when the outcome differs from what we expected.

Imagine someone who has avoided public speaking for years because they expect to become anxious, lose track of their thoughts, and leave the audience unimpressed. Eventually, they agree to explain a familiar subject in a small team meeting.

The presentation goes better than predicted. The audience asks good questions, the speaker communicates clearly, and someone invites them to lead another discussion later.

That single experience does not prove that public speaking will always be enjoyable. It does show that the person's previous prediction was incomplete.

Expectations Are Predictions, Not Facts

Learning research examines a specific mechanism known as reward prediction error, which involves differences between expected and actual rewards. Research by Wolfram Schultz, Peter Dayan, and P. Read Montague helped establish its connection with dopamine-neuron activity.

The mechanism should not be treated as a complete explanation of ordinary exploration, but the broader distinction is useful. We continuously make predictions about what experiences will feel like and what outcomes they will produce.

When reality differs from those predictions, our next decisions can change. Experiences provide evidence capable of updating expectations.

Avoiding an unfamiliar experience can therefore preserve a prediction simply because nothing has challenged it.

New Experiences Test Identity

Predictions about ourselves can be especially persistent.

Someone says they are not creative, bad with technology, uncomfortable around strangers, or incapable of public speaking. The description may reflect substantial experience, but it can also depend on a limited or outdated set of observations.

Trying something unfamiliar generates new evidence.

A person who describes themselves as shy may take an acting class and discover that prepared performance feels comfortable while spontaneous conversation remains difficult. That is a more precise description than deciding they are simply either shy or outgoing.

Someone who struggled with technology years earlier may discover that the abilities or tools involved have changed enough to make the old conclusion inaccurate.

Exploration Can Refine Identity

The purpose of testing identity is not to prove that every self-description is false. Some experiences confirm what we already believed.

Someone can try painting and discover they genuinely dislike it. Another person can experiment with public speaking and conclude that it remains an unpleasant use of their time.

That is still information.

Exploration helps turn broad identity claims into better-supported conclusions. It replaces assumptions with evidence and can reveal conditions under which a trait or preference changes.

The result is often greater precision rather than dramatic transformation.

Trying New Things Has Real Costs

Exploration consumes resources.

Time spent testing one option cannot be spent pursuing another. Courses cost money, career experiments can reduce income, travel requires resources, and failed business experiments can consume capital.

Some choices are difficult to reverse. A person supporting children, carrying substantial debt, or depending on employer-provided healthcare faces a different decision when considering a career change than someone with extensive savings and fewer financial obligations.

Those differences affect the rational cost of exploration. They should not be reduced to differences in courage or curiosity.

People Explore Different Kinds of Uncertainty

Psychologists use the term openness to experience to describe a personality dimension associated with interest in unfamiliar ideas, experiences, and perspectives. That does not mean people possess one universal level of risk-taking across every domain.

Someone may love unfamiliar art and ideas while being extremely cautious with money. Another person may enjoy adventurous travel while preferring predictable work routines.

The willingness to explore depends partly on personality and partly on the consequences involved.

This explains why a person can appear highly adventurous in one part of life and highly conservative in another without contradiction.

The Question Is Whether Discovery Is Worth the Cost

Because exploration is costly, trying something new is not automatically the best choice.

The useful comparison is between the possible value of learning and the cost of obtaining that information. A cheap and reversible experiment can justify exploration even when the probability of finding something better is uncertain.

A costly and irreversible experiment deserves more evidence before commitment. The value of the unknown has to be considered alongside the consequences of discovering the answer.

This turns novelty into a decision problem rather than a virtue.

Small Experiments Can Reduce the Cost

Many large decisions can be tested through smaller experiences.

Someone considering a career change can talk with practitioners, volunteer for a related project, take a short course, or complete a small piece of work resembling the target role. Each test creates information without requiring the person to resign immediately.

A company considering a new product can ask potential customers to commit before building the entire product. Someone interested in a new activity can attend one lesson before purchasing expensive equipment.

The experiment works when it resembles the underlying decision closely enough to teach something important about it.

The objective is not to eliminate all uncertainty. It is to reduce avoidable uncertainty before making a larger commitment.

Not Exploring Has a Cost Too

The risks of action are usually more visible than the risks of inaction.

Trying an unfamiliar career can fail. Remaining in a familiar one can also have consequences if the work becomes less rewarding, the industry changes, or an untested alternative would have fit better.

Testing a new business strategy can waste resources. Never testing alternatives can leave a company dependent on an approach whose effectiveness is declining.

Avoiding experimentation therefore preserves uncertainty rather than eliminating it.

Sometimes that is the correct choice because finding out would cost too much. Other times, remaining uncertain is more expensive than running the experiment.

What Would You Never Learn?

People try new things for many reasons. Novelty can be pleasurable, curiosity can pull us toward unanswered questions, and exploration can reveal better opportunities.

The common thread is information.

An unfamiliar experience can tell us something our familiar routines cannot: whether another path works, whether a prediction is accurate, whether an assumption about ourselves still belongs, or whether an opportunity deserves greater commitment.

The best question is therefore not simply whether the unfamiliar option will work.

Ask what knowledge becomes available only through trying it.

What would you never learn if you didn't try?
