There's nothing wrong with being a curious or attentive person who likes to notice things.

What I often see, especially in the social media era, is people who are selectively curious and like to notice negative things. So they'll share lots of articles with titles like "The Amazon Tax", which I agree was interesting and informative, but they're not at all interested in e.g. "How Amazon Is Bringing Fast Delivery to Rural America" (https://www.wsj.com/business/logistics/how-amazon-is-bringin...). That's more of a problem, and I think it's what drives the idea that truth-seekers are less happy.
