Final answer:
The term for someone who does not contribute their fair share to a group project and benefits from others' work is a 'free rider.' This issue contributes to the collective action problem, where individuals in a group experience a disincentive to contribute while benefiting from the collective effort.
Step-by-step explanation:
The technical term for an unhelpful person on Calvin's team who does not want to contribute his fair share is a free rider. This term describes the behavior of accepting a benefit without contributing to its achievement. The free rider problem becomes evident in group assignments where certain individuals do minimal work yet reap the same rewards or grades as those who contribute significantly more effort.
This issue not only occurs in academic settings but also in other collective scenarios such as organizations, government, and public initiatives. For instance, when a community effort or organization like National Public Radio (NPR) needs funding, not everyone contributes, resulting in some individuals free riding on the contributions of others. Similarly, within an academic context, all members of a group project receive the same grade, which can discourage individual effort, leading to collective action problems and potential inequity in work distribution.
