An epidemic of this time is the inability people to classify the intent of information. You need to do a better job of knowing when someone is intending to give first hand facts (eye witness), insider facts (second hand info), insider speculation (someone with internal info speculated that), speculation (someone without insider info / I speculated that), opinion (emotional response).
That is on you to determine. Look at the wording:
It is my sense that (speculation)
Word around the league is that so and so will be traded (insider speculation)
A source close to the team has indicated that so and so is on the trade block (insider fact)
A quote from a person / imminent event (first hand fact)
Consider job titles:
Insider / Analyst: mostly speculation, should have insider facts / break trades now and the
Reporter: should usually just deliver facts
Columnist/colour panelist: Outsider speculation and opinions. Their job is to provide an angle and entertainment, not to be correct.
When I was in elementary school we were taught how to classify information, and those concepts can be applied to a lot of different industries. Is this just something we forget over time? Just be better at this.
