Let me see if I understand your question correctly. It seems like you're interested in a few key things:

1) Verifying if the reported incident about British people believing spaghetti grows on trees is true or just an urban legend.
2) Understanding how such a deception or misinformation campaign might work, and why people would fall for it if true. What tactics or psychological vulnerabilities were leveraged?
3) Considering the broader implications of widespread misinformation, and how to discern and avoid being misled by such fraudulent claims in the future.

Do I have the gist of your questions and interests right?

If so, here are some key points:

1) This spaghetti tree story seems to be more of an urban legend. While mass deceptions have occurred, I could not find credible evidence that a spaghetti tree hoax happened as popularly reported. It appears to be more of a spoof or thought experiment.
2) That said, there are psychological tactics that can make misinformation campaigns effective, including:
- Appealing to emotions or biases rather than facts (e.g. greed, fear)
- Creating a false sense of scarcity or urgency
- Repeating a claim frequently to make it seem more valid or familiar
- Claiming (fabricated) expert endorsements or evidence to seem credible
- Using social proof that others believe the claim to encourage groupthink
3) The impacts of misinformation can be dangerous, eroding truth and trust. The best ways to discern legitimate information include:
- Considering the expertise and possible motivations of the source
- Corroboration from multiple credible sources
- Considering if a claim seems logically plausible and aligns with scientific consensus
- Fact-checking suspicious stories or statistics to verify the details

Does this help summarize the key takeaways around your questions? Please let me know if you would like me to elaborate on any of the points or discuss other aspects of misinformation and deception. I'm happy to provide more details and insights.
