I agree, especially in this kind of study, where it's been acknowledged (e.g. https://www.tandfonline.com/doi/full/10.1080/09658211.2017.1...) that lies contribute to the formation of false memories.

For example, another commenter reports that his mother seemingly remembers things that never happened; the first thing I thought (because of similar experiences) was that perhaps his mother had lied to friends about family coming over to visit.
