Start with this brief introductory exercise to ground yourself in key context before diving into the CHIRON exercises. This context will help you get the most out of the discussions ahead.

What this introduction covers

What biorepository (or “repository”) research is
The problem of group harm (with examples)
How to use CHIRON in your role
Key term definitions
Activity: the Trustworthiness Calculator

Instructions

This introduction is mostly reading-based. If you’re working in a group, go through it together, either by taking turns reading aloud or reading silently at your own pace. Use the discussion questions as natural pause points to reflect and talk as a group.

Reminder

This is intended for conversations about biorepository enabled research — research that relies on the storage and sharing of biological samples and/or data. You may still find it useful in other contexts.

Biorepository Research

Biorepository research refers to the use of existing biological samples or data — such as DNA, blood, or health records — for research purposes that go beyond the original reason those samples or data were collected. This is often called secondary research.

Unlike primary research, which involves collecting new data directly from participants, secondary research uses existing materials. This makes it easier and faster to conduct — but also more removed from the people represented in the data.

Pause and discuss:
  • What kinds of data do you or your institution work with?
  • In your experience, how closely are researchers connected to the communities represented in their data?

The Problem

Even when researchers have good intentions, studies that rely on large datasets can unintentionally:

Misrepresent certain communities
Reinforce bias or stigma
Lead to inequitable decisions in healthcare or policy

We call these types of effects group harm.

Group harm is different from the kind of harm we often think about in research — like a breach of privacy or a painful procedure that affects someone as an individual.

Instead, group harm refers to the negative consequences that arise because of your connection to a larger group, such as your race, ethnicity, gender identity, sexual orientation, disability status, where you live, the type of work you do, your socioeconomic background, or even patterns in your DNA. In some cases, the group itself may not exist until research instantiates it (like people with the BRCA gene mutation).

Let’s look at a couple of examples of group harm.

Pause and discuss:
  • What went wrong in these examples? 
  • Where in the process could harm have been prevented?
  • How would you explain group harm in your own words?

Key Players

As of now, group harm is not formally recognized in most research regulations. This means that secondary research (studies that reuse existing data) typically does not undergo the same ethics review process required for primary research.

Because there are no formal guardrails to prevent group harm, individuals must make the choice to acknowledge the risk and take steps to mitigate it.

Secondary Researchers

Many choices can unintentionally cause group harm. Researchers must be mindful of the decisions they make throughout the planning, analysis, and dissemination of their research.

Ethics Committees

Ethics committees are not usually required to review secondary research, or to consider group harm. But these committees may deal with secondary research on occasion, or some choose to engage with these issues anyway. (source) Even if regulations don’t require it, ethics committees can shape better norms and advocate for more inclusive practices.

Data Access Committees

Data Access Committees (DACs) are often the only gatekeepers researchers must go through to access repository data. Even if ethics isn’t their official role, they can ask meaningful questions and set expectations for community consideration.


Using CHIRON

CHIRON was created to help people in these roles take meaningful steps to reduce group harm in research. Here’s how we imagine it being used:

How Secondary Researchers Can Use CHIRON

Use the exercises while actively working on a project, or make up a project to discuss. Each exercise will help you think through your decisions with regard to a certain topic, such as choosing a research question, lumping or splitting variables, sharing results, etc.

How Ethics Committees Can Use CHIRON

Use CHIRON as a resource to guide your review process. You might adapt questions or prompts for inclusion in your application materials or discussion checklists. Choose a real research submission to discuss, or make up an imaginary one.

How Data Access Committees Can Use CHIRON

CHIRON can support your role as a safeguard against potential harms. You might integrate it into your review workflow or use specific exercises to inform your deliberations. You might also adapt questions or prompts for inclusion in your application materials or discussion checklists. Choose a real research submission to discuss, or make up an imaginary one.

A Note on Research Roles

We recognize that roles aren’t always clear-cut. A “secondary researcher” may also have been involved in collecting the data, or have other relationships with the community it comes from. You might be both a data steward and a researcher—or a committee member who also conducts studies.

Use CHIRON from the standpoint of your current role, while keeping in mind the full complexity of your work.

Pause and discuss:
  • Which role(s) do you most identify with?
  • Where do you see opportunities to address group harm in your own work?
  • Where do you see challenges to addressing group harm in your work?

Key Terms

Knowing these terms will come in handy while using CHIRON.

Biorepository – Any collection of data that has been amassed for research purposes that includes:
tissue samples and/or data derived from those samples
plus biological and/or health data of any kind.
Biorepository research – Any study that uses data from a biorepository. This research often employs computational techniques like machine learning and artificial intelligence.
Algorithmically-defined community – Groups formed through computational analysis (e.g., “BRCA carriers” or “high-risk patients”) that may not have existed before the research.
Group harm – Harm experienced because of one’s connection to a larger group, rather than their individual identity. Examples include stigma, exclusion, or policy impacts.
Community – A group of people with a characteristic in common. Can include traditional identity-based groups (race, gender, etc.), but also new or fluid categories that emerge from research itself.
Pause and discuss:
  • Are any of these terms new to you, or defined differently than you’re used to?

Activity

Before moving forward, complete the Trustworthiness Calculator. This tool helps you reflect on your current practices and assumptions toward community-centered research. You’ll return to it after completing the CHIRON exercises to see how your perspective has evolved. 

Pause and discuss:
  • How did it feel to answer these questions?
  • What, if anything, surprised you about your score?
Write it down

Record your score somewhere safe so you can revisit it during the wrap-up exercise.


Final Thoughts

CHIRON isn’t here to give you “right answers,” because those will be different for each situation. Instead, it’s designed to help you think critically.
