Competing ideas (1 of 5)
Scientists are more likely to put their trust in ideas that generate more specific expectations (i.e., are more testable).![Image showing force of gravity applied to both apples and atoms.](https://undsci.berkeley.edu/wp-content/uploads/2022/08/79021_evo_resources_resource_image_35_original-350x272.gif)
Competing ideas (2 of 5)
Scientists are more likely to put their trust in ideas that can be more broadly applied.![Example of evolutionary tree showing red feathers evolving twice is less preferable to evolving once on an evolutionary tree.](https://undsci.berkeley.edu/wp-content/uploads/2022/08/69126_evo_resources_resource_image_36_original-350x273.gif)
Competing ideas (3 of 5)
Scientists are more likely to put their trust in ideas that are more parsimonious.![Scientific theories as puzzle pieces.](https://undsci.berkeley.edu/wp-content/uploads/2022/08/93667_evo_resources_resource_image_37_original-350x303.gif)
