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. 🙂

  1. Thanks for the great hint about am biased. I enjoy learning, even at my age. I was brought up to speak and write well, and I appreciate info like this. I wish others that blog would take the time to learn how to do it gooder. 😉

  2. Excellent, nothing irritates me more! If you are using the English language then use it properly, well said Michelle!

  3. Love your 5 minute lessons!!! I learn so much! Since I ignored my teachers in English class when it came to the grammar part. Just give me a story!! My biggest pet peeve is anyway vs. anyways. ARGH!

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


  5. 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?

    1. @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.

  6. 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)

    1. 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.
