Seven disadvantages of focus groups
A list of the seven main drawbacks of focus groups: groupthink, dominant participants, social-desirability bias, small samples, cost, moderator bias and slow turnaround. Use it to decide whether a group session fits your question, or whether one-on-one interviews would get you more honest answers. Koji runs AI-moderated one-on-one interviews in parallel for teams that want the depth without the group effect.
Where this appears
What's in this guide
- Groupthink: People drift toward the first strong opinion in the room, so you record a consensus the group made up.
- Dominant participants: One or two loud voices steer the talk while quieter people hold back.
- Social-desirability bias: People give the answer that looks good in front of others. It's worst on pricing and sensitive topics.
- Small, non-representative samples: Eight people can't be projected onto a market. Treat what you hear as directional.
- High cost and heavy logistics: Recruiting, incentives, a venue, a moderator and eight matching calendars all add up.
- Moderator bias: Small cues from the moderator lead the group, and sessions run by different people stop being comparable.
- Slow time-to-insight: Recruiting, several sessions, transcripts and synthesis can stretch one study over weeks.
