Why economics considered a science

In addition, many social sciences use surveys and other rigid research methodologies to determine trends and provide clarity to future practices.

Among the social sciences, economics is noteworthy for its early and widespread adoption of formal mathematics in its theoretical development and of statistical methods and quantitative computer applications in its empirical approach to applied research. The increased reliance on mathematical models to study the economy began with neoclassical economics in the late 19th century and remains essential to theoretical and applied economics. One of the primary arguments made against classifying economics as a science is a lack of testable hypotheses.

Underlying the difficulty in developing and testing an economic hypothesis are the nearly unlimited and often unseen variables that play a role in any economic trend. The argument against considering economics as a science is based on the fact that controlled experiments cannot be performed in laboratories.

The field of chemistry, on the other hand, offers the ability for chemists to test a hypothesis and evaluate those results. Instead, economists most often analyze historical data either on a nationwide basis or by geographic region. It's this inability to test hypotheses in a controlled environment and the ability to eliminate outside influences that could impact results that makes some argue that economics should not be considered a science.

However, this same critique—that experts cannot perform controlled experiments in a laboratory—could be extended to all social sciences.

For example, even branches of natural sciences, such as physics, have theories that have yet to be proven, but society accepts the branch of physics as a science. Also, the frequency of immeasurable variables in economics allows for competing, and sometimes contradictory, theories to coexist without one proving the other infeasible. While economics increasingly uses scientific and mathematical methods to track and predict trends, conflicting models, theories, and results often prevent economics from reaching solid consensus as found in many of the natural sciences.

However, these discrepancies and conflicts are inherent in any social science—all of which require an element of interpretation rarely found in the natural sciences. The field of economics contains quantitative and qualitative elements common to all social sciences, and as long as social sciences exist as a class of sciences, economics fits within the class.

He discusses the issues behind the failed replication and the problem of replication in general in other fields, arguing that replication is under-appreciated and little rewarded. After a discussion of the incentives facing scientists, the conversation turns to the challenges facing science journalists when work that is peer-reviewed may still not be reliable.

May 4, Ed Leamer, of UCLA and author of Macroeconomic Patterns and Stories, talks with EconTalk host Russ Roberts about how we should use patterns in macroeconomic data and stories about those patterns to improve our understanding of the economy. Leamer argues that economics is not a science, but rather a way of thinking, and that economic models are neither true nor false, but either useful or not useful. He discusses various patterns in the recessions and recoveries in the United States since The conversation closes with a discussion of the reliability of econometric analysis….

Economics is sometimes called catallarchy or catallactics, meaning the science of exchanges. Where did this term first come from? It is with a view to put you on your guard against prejudices thus created, and you will meet probably with many instances of persons influenced by them, that I have stated my objections to the name of Political-Economy.

It is now, I conceive, too late to think of changing it. Levy and Sandra J. Econlib, January 22, Everyone knows that economics is the dismal science. And almost everyone knows that it was given this description by Thomas Carlyle, who was inspired to coin the phrase by T. While this story is well-known, it is also wrong, so wrong that it is hard to imagine a story that is farther from the truth. March 3, Manzi on Knowledge, Policy, and Uncontrolled. Jim Manzi, author of Uncontrolled, talks with EconTalk host Russ Roberts about the reliability of science and the ideas in his book.

Manzi argues that unlike science, which can produce useful results using controlled experiments, social science typically involves complex systems where system-wide experiments are rare and statistical tools are limited in their ability to isolate causal relations.

Because of the complexity of social environments, even narrow experiments are unlikely to have the wide application that can be found in the laws uncovered by experiments in the physical sciences.

Manzi advocates a trial-and-error approach using randomized field trials to verify the usefulness of many policy proposals. And he argues for humility and lowered expectations when it comes to understanding causal effects in social settings related to public policy. Nosek on Truth, Science, and Academic Incentives.
