How Do You Pronounce "Likert?" What is a Likert Scale?
There is a good chance that you have been misprouncing "Likert" for many years. It is properly pronounced "Lick urt," not "Lie kurt." I know this because my professor in graduate social psychology knew the man at U. Michigan and pronounced his name as he did himself. Oh, you don't believe me, eh. Well, check out the links below.
Ray Tucker explains this to his students -- who did not believe him until he got Likert on the phone.

Dear Dr. Wuensch,
I ran across your web page providing the stories and background on the correct pronunciation of Dr. Rensis Likert's name.
I never knew Dr. Likert, however his daughter, Dr. Betsy (Likert) David is married to my coauthor and mentor, Dr. Martin David. Betsy is quite an adamant and forceful advocate of the proper pronunciation of her maiden name!
I appreciate your web site because I can add it to my usual "speal" about how to properly pronounce the name.
I have won many beers with my story. When I mildly say, "It's pronounced LICK-urt" and they reply "Well, I've always heard it as Like-urt" I usually respond, "wanna bet?" I like free beer!
Also, I learned a little about what exactly constitutes a Likert Scale vs a Likert-type scale. Thanks!

This question actually came up on another list a few years ago. The author collated results, and found Americans preferred like-ert, while
Europeans tended towards lick-ert. However, one of the respondents who went for lick-ert happened to be the son of R. Likert, so I've changed my pronunciation since then.
Gary McClelland told me (KLW): I met Rensis Likert at Michigan and he definitely introduced himself to me as "Lick-ert."
My colleague, Rosina Chia, also a Michigan graduate, told me the same.
What is a Likert Scale?
I have always restricted the use of
the term "Likert scale" to those scales where respondents express their
STRENGTH OF AGREEMENT with each of several statements , typically with an
odd number of response options varying from "strongly disagree" to "strongly
agree." I have, however, increasingly seen "Likert scale" used to describe
items with five or seven ordered response options but where the response
scale is not in terms of strength of agreement. For example, where the stem
is "I think about the Flying Spaghetti Monster" and the response options are
"never," "rarely," "sometimes," "often," and "all the time." In your
opinion, are such scales appropriately referred to as being "Likert scales?"
Excellent question! I am not a
statistician, although I pretend to be one whenever I write up manuscripts,
so I would say YES, if you are then applying numbers to those responses and
analyzing those numbers--note careful use of language in that last phrase.
As James Thomas observes, Likert used a very specific procedure: rating of agreement/disagreement empirically-derived scales (Note: his preference being for 5 points, unweighted). Moreover, the central point indicates neutrality, and the ratings were made to unidirectional attitude statements.
Strictly speaking, then, these are the conditions for a Likert scale. I have had recent correspondence on this issue with Marion Aftanas at the University of Manitoba, his concern being the the terms “Likert: and “Likert-type” are used rather inappropriately and somewhat indiscriminately.
In answer to Karl’s question, I do not think that a scale should be called a Likert scale unless it meets Likert’s conditions. “Likert-type” might be better, but it does not specify the degree to which the procedure differs from Likert’s I prefer the neutral term “ordered response scale" for scales that do not meet Likert’s conditions.
The Likert scale was introduced as a scale of attitudes in Likert's "A Technique for the Measurement of Attitudes," Archives of Psychology, No.140, 1932. It was a bipolar scale running from one extreme through a neutral point to the opposite extreme. I think it is the bipolar nature of the scale that makes it a Likert scale, not so much whether it is measuring attitudes . Such a scale was not new with Likert, though. Titchener used the same kind of descriptive scale to analyze feeling experiences, running from pleasant to unpleasant through a neutral point. Wundt did something similar even earlier on the descrption of feelings. Still, Likert used a numerical coding for his scale, something Wundt and Titchener did not do and used it, of course, for attitudes.
A scale that is unipolar going from low agreement to higher agreement would be more properly called a Guttman scale, since it was popularized by Guttman in 1944. I am sure it has earlier incarnations, but he used it first, I believe, in attitude scaling. So, the linear scale with no central zero point you use in your example is a Guttman scale.
Karl, my understanding is that the Likert scale has five points from
strongly agree to strongly disagree. Those with 6 or 7 or 8, etc. are
Likert-type scales. The Guttman scale is unidimensional.

Karl, I agree with your take on this. The Likert Scale is a measure of attitudes, preferences, and subjective reactions by eliciting a response along the lines of strength of agreement with the scale items. I don’t think the mere use of questions that have multiple response items are necessarily Likert Scales.
I have checked several books and don’t find a succinct definition of a Likert scale but would agree with your first example. However, I am probably guilty of using the term Likert or Likert-like for the second case.Michael Poteat
As far as I know, Likert himself used strength of agreement ratings for his scales. However, I’m not sure I see a difference between the two examples. If the statement is reworded as “I often think about the Flying Spaghetti Monster” and I rate strength of agreement, wouldn’t the scale provide the same information as the never/rarely/sometimes/often/all-the-time scale? I suppose it’s an empirical question to which I don’t have an answer. If you find the answer, I’d like to hear it.
P.S. Andrea and I are jonesing for some more peter peppers.
P. P. S. I’ve been thinking of the Flying Spaghetti Monster obsessively as of late.

I think we've become accustomed to using "Likert" to reference multipoint bipolar scales that assess agreement, frequency, and so forth. Likert-type is also used to reference them. You might check Bert Green's article on the measurement of attitudes in the Handbook of Social Psychology from the 70's (Bill Grossnickle has a copy and referenced it in his Social Psyc grad class until fairly recently).
