Common cognitive biases: sound familiar?

You follow the majority without checking whether you agree with their reasoning.

Anchoring bias

The first number or piece of information you hear shapes your judgement, even if it has little to do with the issue.

Availability bias

Something seems more likely when it comes readily to mind. For example, because you've just heard about it.

Overconfidence

You overestimate your knowledge or abilities and overlook risks as a result.

Would you start the campaign again today? Consider whether the next investment is worthwhile, regardless of what you've already put in.
