Devise a scheme to identify mis/disinformation and blatant propaganda on various online platforms. Are there for example questions you can ask to validate the trustworthiness of a piece of news? Do you need to factor in the nature of the platform and its user base to make that decision? For example would the high amount of bots derailing the discussion (e.g. on 4chan), or the vocal minorities that act as lynch mobs censoring everything against their narrative (e.g. twitter) decrease the trustworthiness of information? If you compare those services to something like quora, which has many self-proclaimed experts would that be enough to systematically repel the misinformation using objective reasoning? Quora as well has it's downsides since it encourages spamming questions (on the English quora). Sometimes verifying information could require reading scientific papers on arxiv or other places. Are there common key points, or pitfalls to look for in any single paper?
To identify misinformation and propaganda on online platforms, you can follow these steps:

1. Verify the source: Check if the source of the information is credible and reliable. Research the author and the organization behind the article.

2. act-check: Use fact-checking websites, such as PolitiFact, FactCheck.org, or Snopes, to verify the accuracy of the information.

3. Look for other perspectives: Check for news articles and opinions from multiple sources to get a more well-rounded view of the topic.

4. Watch out for red flags: Be wary of sensational headlines, emotive language, and unverified claims.

5. Consider the platform: The nature of the platform and its user base can play a role in the credibility of information. A platform with a high number of bots or a vocal minority can decrease the trustworthiness of information.

For scientific papers, you can follow these key points to evaluate their credibility:

1. Author credentials: Check the author's qualifications and research background to assess their expertise.

2. Peer review: Look for papers that have been peer-reviewed by experts in the field.

3. Evidence: Check if the paper provides evidence to support its claims, and if that evidence is based on rigorous methodology and data analysis.

4. Replicability: Look for papers that describe their methods in enough detail to allow for replication by other researchers.

5. Potential biases: Consider if the authors have any potential biases or conflicts of interest that might affect their findings.

Overall, it's important to be critical and skeptical of information, and to approach any piece of news or scientific paper with a critical eye.
Thanks! Also, I mentioned Quora before, it actually has a lot of misinformation around certain topics as well, especially around China, due to the Chinese Communist Party, which often hire people to basically advertise on platforms such as Quora. Do you have any ideas on how to remedy this?
