Know that many stations are biased. Political affiliations, Religious views, and, all the impolite conversation topics that we’re supposed to veer away from usually affect what gets relayed to the general public. Some advertise themselves as being balanced news stations just to portray the same sense of bias.
Watch more than one news station that have differing opinions, also listen to more than one radio station. If you are conservative, listen to both conservative and liberal stations to get a better idea of what is going on, and visa versa.
Know that even with listening to more than one station that this is media. They can and will take information and twist or turn it to best interest the crowd and get good ratings. Take things with a grain of salt. If you are particularly interested or appalled by something the media is reporting, do your own research via online or the library to find out both sides of the story, and after seeing different media stations spin on things, try to find cold hard facts out for yourself, and see what you think about it.
Know your politics. Political campaigns can be the worst. Arguments divide friends, and family members alike, and we are all getting information from whatever media happens to be spitting out slander, lies, or popular gossip. Several websites are dedicated to pointing out the facts of what each candidate ACTUALLY says and does, vs what they are accused of or claim. These sites are completely not biased and point out truth and lies of each candidate.
