Matthew Effect
The Matthew effect is cumulative advantage: early gains bring more resources, recognition and chances to succeed, widening initial gaps. Robert K. Merton named it in 1968 to describe scientific credit, where established researchers gain more recognition than their lesser-known peers.

01You've seen this when…
- in life
Your child finds reading easy and starts choosing books for fun. A classmate who struggles avoids them. By the next school year, the difference includes hundreds of hours of practice.
- at work
Two analysts develop a proposal together. The better-known analyst presents it, gets the credit and is invited to lead the next project. The other keeps doing work behind the scenes.
- out in the world
A foundation favors charities with strong fundraising records. Established organizations get another grant, hire fundraising staff and return next year with an even stronger record.
02The idea
An early success can do more than reward what someone has already achieved. It can change what they get to do next. Recognition brings invitations. Funding buys equipment and time. A visible assignment produces the experience needed to win another visible assignment.
The Matthew effect is this accumulation of advantage: having more helps you obtain more. Meanwhile, an early setback can leave someone with fewer chances to demonstrate what they could do. Small starting differences can grow until people’s careers diverge and large gaps open in their skills and resources.
Robert K. Merton introduced the name to explain scientific credit. An established scientist could receive disproportionate recognition for work done with a less-known collaborator, or for a discovery made independently by several researchers. That recognition then strengthened the established scientist’s position.
The wider pattern is a reinforcing feedback loop. Yesterday’s outcome becomes an input into tomorrow’s selection. Unlike a one-time halo effect, it changes the opportunities available, not just someone’s impression of you. The resulting gap can reflect both differences in performance and differences that the selection process itself has created.
03Why it happens
- A familiar name is easier to choose. Reviewers, customers and managers cannot examine everything closely. Prior recognition becomes a shortcut for quality. Choosing an established winner also feels easier to defend if something goes wrong.
- Resources improve the next attempt. Money, equipment, skilled colleagues and uninterrupted time can produce better work. An initial award may create the later quality that seems to justify it.
- Connections bring opportunities. Successful people meet other successful people, hear about openings earlier and receive introductions. Their social capital grows along with their achievements.
- Attention attracts further attention. People encounter work that others have already noticed. In networks, newcomers often connect to already well-connected participants, a mechanism called preferential attachment.
- Setbacks can reduce participation. Rejected applicants may apply less often, struggling readers may practice less, and overlooked employees may stop volunteering. The next contest then contains fewer of the people who lost the first one.
These routes can operate together. A small advantage in visibility earns a resource advantage, which improves performance, which earns more visibility. The compounding matters more than the size of the first difference.
04A worked example
Thijs Bol, Mathijs de Vaan and Arnout van de Rijt studied applicants to the Dutch Veni program, which funds early-career researchers. Their 2018 study compared applicants whose scores fell just above the funding cutoff with applicants just below it. These were close contenders with similar scores, separated by an award threshold.
What it looks like The first grant identifies promising researchers, who then build stronger funding records. Later selection rewards that apparent promise again.
What’s actually going on Near-threshold winners accumulated substantially more research funding over the following eight years than near-threshold nonwinners. The researchers did not find a corresponding advantage in publications and citations. Nonwinners were also less likely to apply for subsequent funding. The initial decision helped shape later participation and success among applicants who began as close contenders.
The cutoff comparison strengthens the causal case because applicants immediately on either side were similar in their assessed quality. It does not make publications and citations perfect measures of research quality, or prove that every later award was misplaced.
What would have helped Treating a previous award as evidence of prior selection and seeking separate evidence of present merit. A funder could examine whether its rules repeatedly exclude close contenders, offer routes back into competition and assess proposals without prominent award histories where feasible. The study leaves the effectiveness of these possible responses unresolved.
05How to spot it
06What to do about it
- Separate current evidence from inherited status. Decide what the task requires before examining names, employers or awards. Use blinding where reputation adds little useful information.
- Account for unequal opportunities. Assess what someone accomplished with the resources available. Ten papers with a large team and five papers working alone are not directly comparable achievements.
- Create another entrance. Reserve some opportunities for newcomers, rotate visible assignments or support promising people who narrowly missed selection. Do not make previous access the only route to future access.
- Record contributions while the work happens. Name who designed, analyzed, built and checked the work before the most visible person becomes its default author.
- Follow the near misses. Check whether rejected candidates keep applying and whether selection predicts later performance beyond the resources it supplies.
- Build evidence others can inspect. If you lack recognition, a work sample or small trial can help someone evaluate you without relying entirely on credentials.
The aim is to preserve the rewards of success while keeping success from becoming a closed admission rule.
07When it isn’t evidence of unfairness
Unequal outcomes alone do not establish a Matthew effect. People can differ in skill, effort, goals and preferences. To identify cumulative advantage, look for a pathway through which an earlier advantage changes later opportunities or results.
Such pathways can be beneficial. Practice improving skill is useful. Giving a capable researcher good equipment can benefit everyone. Unnecessarily restricting access or miscrediting contributions raises fairness questions, and substituting prior selection for fresh evaluation raises the same concern.
This is also different from survivorship bias. Survivorship bias hides people who disappeared from the sample; the Matthew effect helps explain how some people gained advantages while others fell behind. Both can make a winner’s history look more inevitable than it was.
08Roots
In the 1960s, sociologist Harriet Zuckerman interviewed Nobel laureates about their scientific careers. Among the subjects was a delicate problem: whose name receives credit when a famous scientist works with someone less established? The laureates’ accounts made clear that recognition did not always follow the division of labor.
Robert K. Merton drew on those interviews in his 1968 Science paper. He named the pattern after a passage in the Gospel of Matthew describing those who already have receiving more. The striking detail was that eminent scientists themselves could recognize the imbalance: their names attracted credit that might otherwise have gone to colleagues. Zuckerman’s research was central to making the pattern visible, although the label is usually attached to Merton.
The idea traveled beyond scientific recognition. Keith Stanovich used it to describe widening differences in reading development, where early skill encourages the practice that builds later skill. Merton’s later work explored cumulative advantage more broadly. Today the same question connects funding, education and careers: how much of the next success comes from what the last success made possible?
09How solid is this?
Cumulative advantage is documented in scientific recognition, funding and other settings, including near-threshold grant comparisons. Its strength and mechanisms vary. Establishing it requires evidence beyond unequal outcomes.
