Bias

Think critically about everything you read. Be alert to persuasive techniques and advertising.

Many commercial sites provide positive information only about their products or organisation. This is generally accepted, but be aware of one-sided arguments and presentations. Ask yourself, "Who is providing this information and for what purpose?" 

You should look for:

• argumentative or persuasive tone
• stereotypes or demeaning labels 
• sweeping statements or generalisations
• obvious conflicts of interest.

In conclusion

Go with your feelings. If you have any doubts about the purpose or credibility of a site, you should try to confirm its validity, or look elsewhere.
