My thoughts in this post are my own, and not reflective of tulpa.info.
Time of creation and accusations of roleplaying
Back in the day, tulpas took hundreds of hours to create, and before you even started narration, you spent significant amounts of time on form. The end result was imposition, and possession was known as metaphysical roleplaying. Actually, a lot of people were accused of roleplaying.
Back in 2011-2012 parallel processing was more or less the expectation, and you would ignore the mindvoice and only listen when they were capable of auditory hallucinations or at the very least a mindvoice with that "alien feeling." Of course, anyone who put less than hundreds of hours into tulpaforcing were accused of roleplayers, so we decided to have an experiment:
we did this: https://justpaste.it/1a1m
The result of that meddling without any frontloading? This kind of thing: https://community.tulpa.info/topic/1705-me-and-serena-defying-faq-man-progress-report/
I think at that point it started being apparent that the personality aspect of a tulpa is directly related to narration ), not visualizing its form.
With all the heartache those quicker tulpas dealt with for being accused of roleplaying were justified in their cries, as it was indeed possible for a tulpa to be created much quicker, since people were just bypassing the steps that take longer.
I guess my opinion that "a tulpa can be created much more quickly" is popular, but this time period set a precedent of "no doubting: ever" which can persist to this day. I'm not sure that is healthy, but now you have a history lesson.
Now tulpas were being created even more quickly, and once people got to vocality they didn't seem interested in imposition or even working on form anymore-- they usually go straight to things like possession, switching, or just socializing. Should that be all we're aiming to get to?
I feel like spending significantly more time on things like visualization can help develop the mind's eye in general--- meditation is good for the brain. Before I started tulpaforcing, I couldn't visualize for crap, but after several 3-hour sessions of sitting with my eyes closed and visualizing Chess, I was able to get to the point where my mind's eye was as vivid as a lucid dream.
I also keep hearing how there's people in the community who had a tulpa 4-5 years ago and no longer have them. Does anyone know if those tulpas were imposed? I could be dead wrong but but I'm wondering if taking more time, effort, and attention would be a factor. This also goes into things like parallel processing: what is the correlation between tulpas who are able to "parallel process" and tulpas who are fully imposed? Don't get me wrong, I think it's good to see more tulpas out there, but how many are capable of talking in the ear 3d of the host audio style? Does it matter? Maybe not, but for me personally I would like to see it more.
Nature of a Tulpas
I don't know how popular of an opinion this is anymore, but I believe that a tulpa is a separate and parallel mind to their host. I don't think they're a part or aspect of the host, but a different person, and the only difference between a tulpa and a host is that the host was there first. I outlay most of my rationale for that from observation touched on in my Neuroscience lecture many years ago.
Likewise I also believe that parallel processing is a thing. Yes, there's a clear limitation on working memory (e.g. ones individual consciousness), but that limitation definitely does not seem to be a limitation of the brain (which seems to process basically everything, even at a high level, before disregarding it and sending it to the conscious awareness). I can't prove this, so I'm not super vocal about it, but I'm pretty sure that argument can be supported with cognitive psychology if we play our cards right.
