Thesis statement: Using the Internet gives young adults increased literacy but also leads to health problems and isolation from other people.

Evidence: Feeling isolated, many teenagers turn to drugs or gang membership to solve their problems, according to interviews conducted by Smith and Paget at the Outsider’s Café.

Is this evidence effective/ineffective?

Question

Thesis statement: Using the Internet gives young adults increased literacy but also leads to health problems and isolation from other people.

Evidence: Feeling isolated, many teenagers turn to drugs or gang membership to solve their problems, according to interviews conducted by Smith and Paget at the Outsider’s Café.

Is this evidence effective/ineffective?

BlackTom AI · Accepted Answer

Effective evidence must be credible, relevant, and sufficient to support the specific claim in the thesis.

1. Relevant knowledge points and concepts
- Relevance: Evidence must directly connect to the claim (Internet use → isolation/health problems).  
- Credibility: Source should be reliable (academic study, representative survey) rather than anecdotal.  
- Sufficiency and generalizability: Evidence should be broad enough (sample size, methodology) to support a general claim about young adults.  
- Causation vs. correlation: Showing that isolated teens use drugs/gangs does not prove the Internet causes isolation or health problems.

2. Step-by-step reasoning applying those concepts
- Step 1 — Check relevance: The thesis links Internet use to isolation and health problems. The evidence reports that isolated teenagers turn to drugs or gangs. That only addresses consequences of isolation, not whether Internet use causes that isolation or health problems. So relevance to the causal claim is indirect and incomplete.  
- Step 2 — Check credibility: The source is “interviews conducted by Smith and Paget at the Outsider’s Café.” This appears anecdotal, likely small, self-selected, and context-specific, so it lacks the rigor of a scientific study.  
- Step 3 — Check sufficiency/generalizability: Interviews at one café cannot be generalized to “many teenagers” or to the population of young adults using the Internet. Selection bias and lack of methodology make the evidence insufficient.  
- Step 4 — Check causation: The evidence shows a correlation (isolated teens sometimes use drugs/gangs) but doesn’t link isolation to Internet use or to health problems described in the thesis.

3. Intermediate “checklist” steps (no numeric calculations)
- Relevance: Partial (addresses isolation consequences but not Internet link).  
- Credibility: Low (anecdotal interviews).  
- Sufficiency: Insufficient (small, non-representative sample).  
- Causation: Not established.

4. Why the correct answer is correct
Because the evidence is anecdotal, non-generalizable, and fails to establish that Internet use causes the isolation or health problems named in the thesis, it is ineffective.

5. Why the other option is incorrect
Labeling it “Effective” would ignore lack of representativeness, missing causal link, and weak source credibility—problems that make the evidence unsuitable.

6. Conclusion
Therefore the evidence is Ineffective, which matches the provided answer.
