What methods can you use to ensure a fair and unbiased code review process?

1 Define clear and consistent standards

Before you start reviewing or submitting code, make sure you have a clear and consistent set of standards that everyone agrees on and follows. These standards should cover aspects such as coding style, naming conventions, documentation, testing, error handling, and security. Having a shared code style guide, a linter, and a formatter can help enforce these standards automatically and reduce the need for subjective or trivial comments. You should also define the scope and purpose of each code review, and communicate them clearly to the reviewers and the reviewees.

2 Use tools and techniques to reduce bias

One of the challenges of code reviews is to avoid bias, such as favoritism, prejudice, or personal opinions, that can affect the quality and objectivity of the feedback. To reduce bias, you can use tools and techniques such as anonymizing the code, using a checklist, asking open-ended questions, and giving constructive criticism. Anonymizing the code means hiding the identity of the author and the reviewer, so that the focus is on the code itself, not the person behind it. Using a checklist can help you cover all the important aspects of the code review, and avoid missing or skipping anything. Asking open-ended questions can help you understand the reasoning and context behind the code, and invite discussion and clarification. Giving constructive criticism means providing specific, actionable, and positive feedback, rather than vague, negative, or personal comments.

3 Encourage feedback and collaboration

Code reviews are not only a way to check the quality of the code, but also a way to learn from each other and improve your skills. Therefore, you should encourage feedback and collaboration among the team, and create a culture of trust and respect. You can do this by soliciting feedback from multiple reviewers, with different perspectives and expertise, and by giving feedback to others, even if you are not assigned as a reviewer. You can also use tools such as pull requests, code annotations, and chat platforms to facilitate communication and discussion during the code review process. You should also acknowledge and appreciate the feedback you receive, and act on it accordingly.

4 Review your own code first

Before you submit your code for review, you should review your own code first, and make sure it meets the standards and expectations of the team. You can use tools such as code editors, debuggers, and testing frameworks to check your code for errors, bugs, and inconsistencies. You can also use techniques such as self-explanation, rubber ducking, or peer programming to improve your understanding and logic of your code. Reviewing your own code first can help you catch and fix issues early, and save time and effort for both yourself and the reviewers.

5 Be respectful and professional

Code reviews can be stressful and emotional, especially if you receive or give feedback that is harsh, unfair, or unwarranted. However, you should always be respectful and professional, and avoid taking or making feedback personally. You should remember that the code review is not a judgment of your worth or ability, but a way to improve the code and the project. You should also avoid arguments, conflicts, or insults, and instead focus on finding solutions and compromises. You should also be mindful of your tone, language, and timing, and avoid sarcasm, jokes, or criticism that can be misunderstood or offensive.
