If it is, then there's usually someone else that has evaluated the information. Also, these sites are not normally trying to sell something that could slant their information.

"Dry cleaners use a chemical called perchloroethylene, which is toxic.They now have a washer that uses liquidified carbon dioxide that will do the job cheaper and safer." |

Judging
the validity of information: A
lot of information tries to look and sound official, scientific, or
humanitarian, but on closer inspection you begin to see things that
make you wonder. Give five clues that make you suspicious of the information
on Web site or anywhere for that matter? Answers (cues that make you suspicious
are): 2. Fantastic claims (When things sound too good to be true, then they probably aren't true.) 3. Something is being sold (when money is at stake, there is more incentive to be deceptive) 4. Scare tactics (sites that seem to dwell on danger and fear) 5. Non-balanced discussion (When only one side is presented, then someone is probably biased and the whole truth isn't told) |

The validity of fantastic stories can be checked out at these mythbuster sites: http://hoaxbusters.ciac.org The mythbusters TV show has started a Wiki to report on
the results of their tests. So far there's not much entered yet, but it's
worth checking on. |

Below are areas that have a high percentage of misinformation and bogus products. MAGNETS: Anything that deals with the power of magnets should be suspect. This is especially true in these areas: fuel economy, healing of any kind, and water softening. FUEL/MILEAGE BOOSTERS: Anything that claims to increase fuel economy by some high percent (40% or more) is probably bogus. ENERGY: Anything that talks about free energy is suspicious unless there's some clear source such as solar or wind. FILTERS: Any mention of water "conditioning" is bad. Even legitimate products are often overrated. FOOD/NUTRITIONAL SUPPLEMENTS and HEALTH PRODUCTS: Many of these are poorly regulated and unscrupulous companies can really take advantage of your sickness or poor health. BEAUTY and WEIGHT LOSS PRODUCTS: Most take too long to see results. By the time you realize that, the company is no longer in business or ignores you. ANY POPULAR ITEM: Anything that is selling well will attract con artists to sell fakes or simply take money and not deliver. ANY HOT TOPIC: For example, right after Katrina, all kinds of bogus products came out to "help" people survive.
