Advanced Research Techniques

Effective Question Formulation

Poor Question: "Tell me about climate change"

Better Question: "What is the scientific consensus on the primary causes of climate change based on peer-reviewed research from 2020-2025?"

Best Question: "According to recent meta-analyses, what percentage of climate scientists agree that human activities are the primary cause of global warming, and what are the main areas of disagreement?"

Specificity: The more precise your question, the more useful the AI response.

Source Evaluation

AI helps, but verify:

• Authority: Check author credentials and institutional affiliation
• Currency: When was the study published?
• Methodology: Was it peer-reviewed? What was the sample size?
• Bias: Who funded the research?
• Citations: How many times has it been cited?

Golden Rule: Never cite a source you haven't at least skimmed personally.

Cross-Referencing Strategies

Use multiple AI tools for validation:

1. Perplexity: Get broad answer with sources
2. Consensus: Verify if there's scientific consensus
3. Scite: Check how the key paper has been cited
4. Manual: Read the original source

Triangulation: If 3+ tools and manual review align, confidence is high.

Frequently Asked Questions

Q: Can I trust AI research assistants for academic papers? A: AI tools are excellent for discovery and summarization, but you must verify all information and read primary sources before citing them in academic work.

Q: Are AI research tools better than Google Scholar? A: They complement each other. AI tools provide summarization and synthesis that Google Scholar doesn't, but Scholar has comprehensive indexing. Use both.

Q: Will using AI research tools be considered cheating? A: Depends on your institution's policy. Using AI to find and understand sources is generally acceptable; having AI write your paper is not. Always check your institution's guidelines.

Q: How current is the information from AI research tools? A: Perplexity AI: Real-time web search. Elicit/Consensus: Updated periodically (lag of weeks to months). ChatGPT: Training cutoff date unless browsing is enabled.

Q: Can AI research tools access paywalled papers? A: Generally no. They can search abstracts and freely available papers. Access to full paywalled content still requires institutional or individual subscriptions.
