Fallacy of Composition: Understanding the Difference Between Individual and Group Effects

D. 'If I talk loudly at a party, I have a better chance of being heard by my listeners; if everyone at the party talks loudly, everyone can be heard more clearly.'

This statement illustrates the fallacy of composition because it incorrectly assumes that what is true for an individual ('talking loudly increases the chance of being heard') is also true for a group ('everyone talking loudly will make everyone heard more clearly'). In reality, if everyone talks loudly, the overall noise level will increase, making it more difficult for individuals to be heard.
