Show HN: Gauge of the World's Faith in Humanity

I see some positive ones on the negative side too:

"Batman no!! You can't lose your faith in humanity!"

"You must not lose faith in humanity. [...] - Gandhi"

I don't know how the sentiment analysis is being done (naive Bayes?), but perhaps it could be tweaked to handle this case.

Here is a stab in the dark:

These types of declaratives have two negatives side by side (e.g., "not lose", "can't lose"), making them into a positive. They're somewhat similar to rhetorical questions which have assertions embedded in them in the form of a negative question. From the Wikipedia article, "What have the Romans ever done for us?..." (What...ever...?) "...should be read as The Romans have never done anything for us"... (where a negative is surrounded by a verb).

What do people think of this? I'm not entirely familiar with naive Bayes classifier.

Even a tweet about this website itself is categorized as negative: https://twitter.com/LeviDayley/status/313711985437073409

They'll be cancelled out by false positives, eg 'I try to maintain my my faith in humanity. Sometimes I succeed.'
