I look to look at the actual study for such articles. The referenced study for college admission is at https://www.schoolcounselor.org/getmedia/11e887c3-bf04-4345-90c0-432f7dd8d69a/Gender-Ethnic-Bias.pdf .
The study indicates the following analyzed factors were significantly correlated with college admission, listed from highest correlation to lowest correlation in isolation. A positive correlation indicates increased chance of admission (in isolation). A negative correlation indicates decreased chance of admission (in isolation).
Highest Correlation with College Admission
- Difficulty of HS Program: 0.45
- HS Grades: 0.44
- SAT Score: 0.37
- Word Count in LOR: 0.18
- % Achievement Words in LOR: 0.12
- % Standout Adjectives in LOR: 0.03 (not statistically significant)
- % Agenic Adjectives in LOR: -0.01 (not statistically significant)
- % Ability Adjectives in LOR: -0.03
- % Grindstone Adjectives in LOR: -0.08
- % Communal Adjectives in LOR: -0.09
It suggests that LORs may have increased correlation with admission if they have a high word count and many achievement words… but few communal, grindstone, or ability adjectives. The combined multiple variable regression model that controlled for stats found that only word count had a slight positive coefficient with admission. All the adjectives in the LOR had a slight negative coefficient with admission, when controlling for stats. The combined regression model that controlled for GPA, difficulty of HS program, and scores found that ethnicity of applicant had no correlation with the word count (0.00 coefficient). Being female had a very slight positive coefficient of 0.01. More significant was the 0.04 (0.02) coefficient for grindstone words, which was negatively correlated with admission. Recommenders were slightly more likely to use grindstone words when describing female applicants than male applicants, after controlling for stats. Some specific numbers are below for correlation in isolation (not controlled with similar stats).
Correlation with Word Count
- URM Applicant: -0.07
- Male Applicant. -0.03
- Male Recommender: -0.03
Correlation with Grindstone Words
- URM Applicant: -0.01
- Male Applicant: -0.09
- Male Recommender: -0.06
I also included HS grades and SAT scores for a reference comparison.
Correlation with HS Grades
- URM Applicant: -0.22
- Male Applicant: -0.04
- Male Recommender: -0.08
Correlation with SAT Score
- URM Applicant: -0.33
- Male Applicant: +0.02
- Male Recommender: -0.13
In summary it appears that reviewers seem to write slightly more about female applicants than male applicants, which was positively associated with admission. However, recommenders also used slightly more grindstone words (“tireless”, “committed”, …) when describing females, which was negatively associated with admission. With the exception of grindstone words, the degree of difference between genders on LORs was similar to the degree of difference between genders on GPA and scores in this sample.
It don’t think this is good evidence of that we should get rid of LORs, nor does the author of the study. The author does recommend that counselors and teachers be aware of possible biases when writing LORs. However, I do think t that LORs should not be used in isolation, and instead they should serve as an addition to other components of the application.
