Empowering Professional Writing: A Case Study on ChatGPT’s Impact


The advent of AI and machine learning technologies has paved the way for enhanced productivity and efficiency across various professional domains. One such groundbreaking AI tool is ChatGPT, developed by OpenAI, which is designed to assist in a multitude of writing tasks. A recent experiment, as delineated by Shakked and Whitney (2023), unraveled the substantial implications of ChatGPT on mid-level professional writing tasks.


The primary aim was to discern the extent to which ChatGPT could augment productivity, affect skill demand, job satisfaction, self-efficacy, and shape attitudes towards automation among college-educated professionals.


The experiment engaged participants in a controlled setting, where they were tasked with different writing assignments. The participants’ performance, time spent, and grades were meticulously analyzed pre and post the introduction of ChatGPT.


Productivity Enhancement:

  • ChatGPT significantly accelerated the writing process, with 68% of participants submitting the AI’s output without modifications.
  • The time spent on tasks was notably reduced, especially in creating rough drafts, which fell by more than half post-treatment.

Skill Demand:

    • The findings debunked the hypothesis that ChatGPT could be particularly beneficial for individuals with weaker writing skills, as the benefits were uniformly distributed regardless of writing skill level.

Job Satisfaction and Self-Efficacy:

  • Job satisfaction surged by about 0.40 standard deviations post-treatment.
  • A mild and imprecise increase in self-efficacy was noted, by 0.20 standard deviations.

Automation Beliefs:

    • Treatment led to an increment in optimism regarding AI’s productivity enhancement potential by 0.39 standard deviations, albeit with a slight increase in automation replacement worry.

Real-World Application:

Post-experiment, a two-week follow-up survey revealed that 33% of the treatment group participants continued to utilize ChatGPT in their jobs for diverse tasks including generating recommendation letters, responding to customer service requests, and rough-drafting emails. The users rated ChatGPT’s usefulness at an average score of 3.65 out of 5.00.


The Case Study elucidates the substantial potential of ChatGPT in revolutionizing professional writing tasks, fostering a productivity uptick, and generating a positive outlook towards AI-aided working environments. However, the broad adoption and maximized benefits of such AI tools necessitate overcoming challenges like the lack of context-specific knowledge which was reported by some participants.
