Well my experience with the global warming thing has been as Richard described what Vineeto reported:
Moreover, and pertinent to all this, is what feeling-being ‘Vineeto’ reported after the first few weeks of listening to Richard/ reading Richard’s words. Speaking in regards to the effects any and all attempts to fit this totally new paradigm into ‘her’ existing mindset were having, ‘she’ explained the process as being … (1.) as if ‘her’ brain was being turned upside-down … and (2.) how ‘she’ was having to relearn how to think all over again.
Discussion of Non-Actualist Topics
In short, although I grasped most of the individual points of Richard’s article, I thought point 11 missed the mark and wasn’t relevant. I thought the greenhouse effect was a physically possible mechanism, that just hadn’t been proven yet – as opposed to the fact which is that it’s physically impossible, in large part due to this point 11 among others (“In the physical world no externally heated substance can raise the temperature of its heat-source.”).
Finally coming to my senses and accepting fact above feeling with respect to this topic — it felt really extremely wrong at first. Like I was betraying ‘my’ integrity — which ‘I’ was! ‘I’ betrayed ‘my’ integrity to ‘my’ former way of thinking — of which some key elements were:
1 - a hubristic assumption that I am by default right;
2 - an arrogant supposition that I am more well-versed in a topic and know more about it than I actually do;
3 - a prideful presumption that my first reactions are correct; usually followed by
4 - a superficial looking for, scanning of and bare skimming of some internet web-page that seems to agree with what I initially thought, then presented as evidence that I was initially right all along;
5 - a following long convoluted of seemingly-clever-yet-ultimately-just-cunning trains of thought without much regard for facts along the way; leading to
6 - a feeling of certitude in the conclusions derived that way.
However I observed that after doing all these steps, even though my conclusions thereof felt/seemed right… I did not really feel good about them. My “being right” was landing me further into ‘humanity’ not away from it… .which didn’t sit well.
Finally ceasing to do this left me in a state of disorientation, of feeling that I don’t know what is right or wrong in general anymore, of having no solid ground to rely on with my thinking. It felt like 90% of my way of thinking was essentially useless, as in invalid, not an effective way to determine facts and arrive at factual conclusions.
But what I found is that even though I felt disoriented, I was still perfectly capable of – and actually more handy at – sticking to what is factual, and also perfectly fine to live my life the way I had been anyway – i.e. it didn’t interfere with my day-to-day life at all, except being more mentally tired due to constantly reflecting and ruminating on what was happening.
I certainly was disoriented undoing my spiritual conditioning after my first trip to Australia – and I similarly found that sticking to what I knew to be factual despite my feelings, successfully got me through it. But for this topic it seems to have cut deeper – and be over quicker (a matter of days of disorientation rather than months of undoing spiritual conditioning).
I think it is because I really put my all into the topic, trying to figure it out, obsessing over it, putting all my apparent insight and intelligence to the task. So then when I saw I was just completely wrong at the end of it it hit me quite hard 
.
It seems to be a good approach with actualism though – go all-in on something and see where it takes you! Then you know whatever you found at the end is genuine, cause you gave it your all along the way. No excuses can be made that you had reservations or weren’t really trying.
But remember to stick to the facts or you will end up in a strange place .
