Call me a cynic, but the whole "think critically and figure it out for yourself" solution is inefficient at best, harmful at worst. Global warming skepticism is exactly the kind of thing that often occurs when people trust their own judgement more than that of subject matter experts.

There are very effective ways to get high quality recommendations, with minimal effort on your part. Want to get good medical advice? Find two highly regarded medical specialists and ask them independently for a diagnosis and treatment plan. Not two doctors next door. Not two doctors who published random blogs. Two doctors who are highly regarded by their peers and by the wider industry.

Want to get good financial advice? Do the same thing with financial advisors. Looking for good fitness advice? Do the same with fitness trainers or nutritionists. Looking for good software engineering advice? Do the same thing with developers.

Eventually the day will come when you have learnt and grown so much, that you are just as capable as the "highly regarded" experts. When that day comes, feel free to debate the merits of their arguments. But until then, don't try to be an expert at everything. Don't feel pressured to derive every single thing from first principles. That's just not scalable.
