Metascience

society Maturity 13-18 Next article →

Metascience is a special way of looking at how we learn about the world. It is often called "research on research" or the "science of science." Instead of studying plants or stars, metascientists use scientific methods to study science itself. They want to find ways to make research more accurate and efficient. This work provides a bird's eye view of all scientific fields.

By looking at the whole picture, they can see where the process works well. They also find places where it might need to improve.

Metascientists focus on five main areas to help science grow. First, they look at methods to stop mistakes like the misuse of math. Second, they study reporting to ensure researchers explain their work clearly. Third, they work on reproducibility, which means making sure results can be found again. Fourth, they look at evaluation to see how we judge good work. Finally, they study incentives to see how we reward scientists.

This helps make sure people are rewarded for doing things the right way.

The history of this field shows that science is always learning from itself. In 1966, a paper studied 295 medical papers from ten important journals. It found that 73% of those papers had conclusions that were not properly justified. Later, in 2005, John Ioannidis published a very famous paper. He argued that many findings in the medical field might actually be wrong. This paper became the most downloaded paper in the Public Library of Science Medicine.

His work is a foundation for modern metascience.

In the early 2010s, a big problem called the "replication crisis" became well known. This happened when many studies in medicine and psychology could not be repeated successfully. To fix this, new rules and groups were created. For example, groups like CONSORT and the EQUATOR Network now give guidelines for reporting. In 2012, the journal PLOS ONE started a Reproducibility Initiative to help.

These steps help ensure that scientific facts are reliable and true.

Today, metascience is a big part of the open science movement. Many large organizations are joining together to support this work. On July 8, 2025, a group called the Metascience Alliance was announced in London. This coalition includes more than 25 different groups and academic institutions. Over 830 people from 65 countries attended the meeting to discuss it. Their goal is to rebuild public trust in science by making it better.

This work helps everyone rely on the things we discover.
