Earlier quoted context omitted.
One doesn't need to lie over stories to make them inspirational.
Where is the lie? There isn't anything un-true about the title. More to the point, the inspirational aspect of the story is quite worthwhile. You might say the "trailer-park" inspiration is one aspect, the "we don't know everything we think we do, even 150 years later" angle is another aspect, and there is a third, possibly overlooked facet, which is that this opens up immense new opportunities for understanding life…
That's true from a literal standpoint, however the title misleads many people into expecting that the subject isn't just from a trailer park as part of his past, but that he somehow made the breakthrough as a current, stereotypical, trailer park resident, i.e. not highly educated.
If there was an intention to mislead it is a lie.
If it's unintentional, it's just poor headline writing (ambiguous and easily misleading).
