Bias? or Biased?

It’s time for my weekly 5 Minute Grammar Rant. Bias or biased is an error I come across a lot in my college composition classes and in blogs I read. It drives me nuts, honestly.

Bias or Biased - A quick Grammar Lesson

Bias? or Biased?

Here’s the deal. BIAS is a noun. BIASED is an adjective.

A person should never be described as BIAS because ADJECTIVES describe nouns.

It’s proper English to talk about BIASED PEOPLE. A person can BE biased or HAVE a bias. For instance:

  • I am a biased mom and think my kids are the cutest kids on earth.
  • I have a BIAS and think my kids are the cutest kids on the earth.  OR
  • I am BIASED – my kids are the cutest kids on earth.

It’s NOT proper to say –

  • I am bias – my kids are the cutest kids on the earth.

It’s simple! Just remember AM BIASED or HAVE A BIAS. That’s all there is to it. 🙂

Hi Michelle

Hi michelle.actually I am a limited speaker..I have been learing english for a year..anyway I just see your thread and understand what the difference between bias and biased! But I also have seen a word such as bias (vt)..and I am was like"just remember am biased and have a bias"but how does it work when it comes to bias (vt)

Bias (vt) means to create a bias in the object of the verb. For example: "If we administer our political survey only to people with facial piercings, it might bias the results." In this example, the survey results would be biased / have a bias.

This is going to be a tough one... The example is: The judge was biased but he was unbias in his adjudication. Many, including Google and many autocorrects, do not observe unbias as a word. In my view when you take an action you are acting in an unbias manner and when you have a belief you are unbiased or biased. the -ed signifies a past relationship with the belief. Thoughts?

@Kevin, if bias is a verb or a noun, it does not appear correct to add the prefix un ( unbias) to make it an adjective.

Hi Kevin, definitely add the -ed and make it unbiased. :-)

An irritating error very common nowadays is the use of "loose"instead of "lose". Well worth a post.
