I have been very much involved in the HFEA public engagement exercises. When you are considering a broad area, or potential uses and outcomes, it is really important to have proper public engagement, including democracy, dialogue, or however you want to refer to it, where you really get to understand what the public will think about a topic.
When it comes to assessing technical aspects, it will be challenging. It is fine to have a lay member on a panel, but I do not know whether consulting the public about really detailed, technical issues might be challenging. It depends on what the advisory committee’s role is and whether it is to look more broadly at potential uses and outcomes or to focus on the specific techniques that are being used.
