Sijtsma and Pfadt (2021) published a thought-provoking article on coefficient alpha. I make the following arguments against theirwork. 1) Kuder and Richardson (1937) deservemore credit for coefficient alpha than Cronbach (1951). 2) We should distinguish between the definition of reliability and its meaning. 3) We should be wary of overfitting in the use of FA reliability. 4) Our primary concern is to obtain accurate reliability estimates rather than conservative estimates. 5) Several reliability estimators, such as lambda(2), mu(2), congeneric reliability and the Gilmer-Feldt coefficient are more accurate than coefficient alpha. 6) The name omega should not be used to refer to a specific reliability estimator.
