Positivity should require substantiation too
In areas where the majority is neutral and unbiased, people making positive assertions are rarely pressured into substantiation, but those making negative comments are frequently scolded for not citing sources and substantiating their claims. It seems a negative POV is initially suspected incorrect, while a positive view is not questioned to the same extent. Note that this only seems to occur in topics and areas where the default view is neutral. Things like utility products, novels, etc. Not things like the iPhone, a politician, or an ideology — these things tend to polarise opinions, and so are not good examples.
An example of this occurrence is product reviews.
> This is an awesome product. It does everything I need it to do.
Compared with:
> This is a rubbish product. It doesn’t do anything I need it to do.
The second one seems more hostile, angry and totally unsubstantiated. But, in fact, they’re both unsubstantiated. We don’t think to question the former as it puts the product in a positive light.
