Principles of equality, diversity, inclusion and intersectionality (EDII) not only foster a more positive and productive research environment, but also enhance the quality and impact of the research itself. Principles of equality, diversity, inclusion and intersectionality (EDII) not only foster a more positive and productive research environment, but also enhance the quality and impact of the research itself. A varied team brings varied perspectives and experiences, which can lead to more creative solutions and innovative ideas. This variety can enhance the depth and breadth of research questions and methods.A team with diverse backgrounds can approach problems from multiple angles, improving the ability to solve complex issues.Incorporating many and different viewpoints from researchers and research participants can reduce biases, lead to more comprehensive and robust research outcomes and ensure results are more generalisable and applicable to a broader population.An inclusive environment can attract a wider range of talented researchers, enhancing the skill set and expertise within the team.A focus on EDII can foster a more collaborative and supportive environment, encouraging open communication and sharing of ideas.By recognising and valuing EDII principles, research practices align with social and ethical responsibilities, ensuring projects are conducted fairly and respectfully.Research that considers a wide range of experiences and needs is more likely to have a positive impact on diverse communities, improving relevance and applicability. For all of these reasons, and many more, BR-UK has developed a range of guidance documents to help our research team and others consider how to be more equitable and inclusive. We share our documents so that others may use them and we welcome feedback on our approaches by email to our Hub Manager at sancha.martin[@]ed.ac.uk.
