Final answer:
To argue that social problems have tipping points, authors typically use statistical data, cite relevant studies or experiments, and offer anecdotal evidence from historical events or real-world examples.
Step-by-step explanation:
To support the claim that there are tipping points for social problems, an author might use a variety of evidence-based methods. These methods often include presenting statistical data that shows patterns and trends, referencing studies or experiments that illustrate how small changes can lead to large-scale shifts, and providing anecdotal evidence from real-world examples that exemplify a tipping point. Additionally, an author may draw upon historical cases where a critical mass of influences or actions led to significant changes in society. This could involve detailing events that show how incremental steps accumulated over time to reach a transformative moment, or discussing the effects of particular innovations or policies that suddenly changed the behavior or beliefs of a population.
