You'll have to walk me through your logic on that again.

How is repeated exposure more likely to increase positive opinion?

It is more likely to be perceived as a common opinion and then people tend to go with what they think the crowd thinks.

That would work through repeatedly exposing people to positive or favorable news. Aka astroturfing. Aka what I asked about.

Parent comment specified the same news, which makes less sense.

If I hear 100x that MS is buying GitHub, that doesn't make me more likely to respond favorably.

That's one of the basic premises of advertising!

[saint_fiasco]

Suppose it isn't more likely, that it is just random. All Microsoft has to do is pick the one article that has a positive opinion at the top and promote that one.

That's astroturfing. Which is what my original comment was about.
