Just getting caught up on posts. It's been a hectic week.
This is an interesting article to me, since I enjoy the psychological and social aspects of the phenomenon. The mind is really susceptible to false or misleading memories, assuming events are even registered in the first place. Even without purposefully misleading by altering stimuli, you can alter your memories just by remembering them. If you question one detail, it's forever hazy. If you misattribute a detail to the event with enough confidence, then it can be forever a "fact" to you.
I typically like to separate modern stories of UAP from folklore, but this reminds me of a lot of little folk from a lot of cultures. There are tales of humanoid folk across a lot of cultures (elves, duende, yokai, etc.) that have a lot of similarities, including shapeshifting and selective sightings. Often, these entities would appear humanoid one moment then appear as an animal or object on second glance. A group of people could also have different experiences of the same encounter. These entities would also often only show themselves to children or select people open to the encounter. I won't even get into the abduction aspect of a lot of these tales.
It's always fascinated me that there are aspects that unite not just folktales, but UAP/NHI encounters across the world and throughout time. I think it helps show that there is some phenomenon occurring and that a lot needs to go into uncovering the truths behind it.
