Multiple discovery
Encyclopedia
The concept of multiple discovery is the hypothesis that most scientific discoveries and inventions are made independently and more or less simultaneously by multiple scientists and inventors. The concept of multiple discovery opposes a traditional view—the "heroic theory" of invention and discovery
Heroic theory of invention and scientific development
The heroic theory of invention and scientific development is the hypothesis that the principal authors of inventions and scientific discoveries are unique heroic individuals "great scientists" or "geniuses." A competing hypothesis is that most inventions and scientific discoveries are made...

Multiples

When Nobel laureates are announced annually—especially in physics, chemistry, physiology-or-medicine, and economics—increasingly, in the given field, rather than just a single laureate, there are two or the maximally-permissible three, who often have independently made the same discovery.

Multiple independent discovery, however, is not limited to only a few historic instances involving giants of scientific research. Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science.

Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together.
