Show summary

Moore: Conclusion Sunscreen lotions, which are designed to block skin-cancer-causing ultraviolet radiation, do not do so effectively. ████ ██████████ ███████ ████ █████ ████ ██████ ███ ████ ████████████ ████ █████ ███████ ████████ ██ ████████ ██ ████ ████ ███████ ██ █████ ███ ████ ███████ ██ █████ ████ █████

Summarize Argument

Moore concludes that sunscreens meant to block cancer-causing UV radiation aren't effective. She supports this by pointing out that studies show that people who use these lotions regularly get as many skin cancers as those who rarely use them.

Identify and Describe Flaw

Moore compares two groups: people who use sunscreen regularly and those who use it rarely or never. She concludes that sunscreen is ineffective because both groups get the same amount of skin cancer. However, she assumes the only difference between the groups is sunscreen use, ignoring other potentially relevant factors, like sun exposure or genetic predisposition to skin cancer.
