Analyzing what people say is pointless?
For starters, that's what every scam artist, con merchant, used car salesman and advertising executive relies on: people who don't use their critical faculties in weighing up what is being touted.
Critical thinking calls for a persistent effort to examine any belief or claim in the light of the evidence that supports it.
There is a TV documentary series on the Crime Channel, called American Greed. In one, across America, $140 million was turned over to one scammer, who dangled the carrot of a 250% !!!! return on their money.
They lost their life savings and retirement money because they didn't think about and ask themselves, but how is a 250% return possible?
I think it's poor teaching if your teacher responds, "It's not what I wanted." And equally, a poor attitude on your part to respond with a sweeping dismissiveness - it's all bull - if you're having difficulty understanding what is required: there's a difference between critical thinking, and creativity, and a place for each. You don't respond to a scammer's hype simply with a creative imagination that is off dreaming how you'll spend your fortune.
