What Makes Programmers Laugh? Exploring the Submissions of the Subreddit r/ProgrammerHumor

TL;DR

This study analyzes nearly 140,000 Reddit posts from r/ProgrammerHumor to understand what makes programming-related content humorous, revealing the complexity of predicting humor and highlighting factors like timing, topic, and humor theories.

Contribution

The paper provides a large-scale analysis of programming humor on social media, applying NLP and regression models to identify factors influencing humor and discussing challenges in automatic humor prediction.

Findings

Image-based submissions tend to score higher in humor.

Humor scores vary with season and time, peaking in winter and early afternoon on weekends.

Topics related to learning and humor theories like superiority and incongruity are significant.

Abstract

Background: Humor is a fundamental part of human communication, with prior work linking positive humor in the workplace to positive outcomes, such as improved performance and job satisfaction. Aims: This study aims to investigate programming-related humor in a large social media community. Methodology: We collected 139,718 submissions from Reddit subreddit r/ProgrammerHumor. Both textual and image-based (memes) submissions were considered. The image data was processed with OCR to extract text from images for NLP analysis. Multiple regression models were built to investigate what makes submissions humorous. Additionally, a random sample of 800 submissions was labeled by human annotators regarding their relation to theories of humor, suitability for the workplace, the need for programming knowledge to understand the submission, and whether images in image-based submissions added context to the submission. Results: Our results indicate that predicting the humor of software developers is difficult. Our best regression model was able to explain only 10% of the variance. However, statistically significant differences were observed between topics, submission times, and associated humor theories. Our analysis reveals that the highest submission scores are achieved by imagebased submissions that are created during the winter months in the northern hemisphere, between 2-3pm UTC on weekends, which are distinctly related to superiority and incongruity theories of humor, and are about the topic of "Learning". Conclusions: Predicting humor with natural language processing methods is challenging. We discuss the benefits and inherent difficulties in assessing perceived humor of submissions, as well as possible avenues for future work. Additionally, our replication package should help future studies and can act as a joke repository for the software industry and education.
