Andrea Floris, I don't know.who you are, but thank you for writing this. I hope it reaches the people who need to read it! www.linkedin.com/posts/andrea...
UK academics should stop being "managed" by managers, who are, with very few exceptions, mediocre, incompetent, and with no academic vision. When I tell foreign colleagues and friends what happens in our universities, they are speechless. Managers who earn far more than £100k per year, who do not listen to academics, who patronise them as they were their children. I have recently seen full professors being dismissed in ridiculous top-down "meetings", where the manager expects only questions and not ideas.  Managers who jeopardise the lives of staff and their families, determining the closure of entire departments. Managers who all speak the very same language, mumbling about "reshaping the future" or "transforming the University into agile institutions", and who want to "create universities of the 21st century in a rapidly changing times".  You hear these bs from all of them, without exception. To cover cuts and redundancies. They are unable to even tell the truth, or describe things as they are, providing a bad example to our young students, who then think that an ethical behaviour, also in language, is not necessary. *These* managers are failing, not the academics. Managerialism is the single most important reason for stress in UK universities, in what would otherwise be a fantastic job where you teach young people and do your research. Until this is fully understood, even by academics themselves, the decline of the UK academic will contunue and a collapse is inevitable.

Humans are not black boxes. Experience is everything. This is not a definition problem. This is a "completely ignoring human experience" problem. Some things cannot be measured objectively (yet). Until then, qualitative evidence is the most important evidence we have.

The business model of higher education is real, and it's depressing for academics who have a love for knowledge and see the greedy leaders at the top who just see the bottom line. Students and staff suffer under this model. If you think it's all fine, you've got your head in the sand.

Welcome to the world of Ganzflicker... in comic form!? Comic by the fabulous daltonkaygreta@gmail.com, Instagram: @Mr.dog.art A MassArt initiative led by @hudrewthis.bsky.social Hallucinations are often feared and unwanted... But what if we could induce them, so we can better understand them?
Narration:
Hallucinations are complex phenomena occurring involuntarily to individuals with a mental disorder. They are often feared and unwanted. 

Narration:
 But what if they can be controlled? What if we could intentionally induce them in a secure way, so we can better understand them?

Narration:
In order for an experimentally induced hallucination to form, the mind must be presented with something specific that is visually very different from what it is accustomed to seeing.

Narration:
Sensory deprivation: The lack of stimuli (specifically visual). Participants engaging in this method of hallucination induction can be completely blindfolded or left in a pitch black environment. Either way, their mind must not be exposed to light.

Narration:
Ganzfeld: A uniformly colored, luminary visual field (e.g. a clear blue sky or a singular color on a screen). Exposure to ganzfeld can induce slight visual hallucinations. 
(Figure laying on the grass, facing a clear blue sky.)

Narration:
Sensory deprivation can be an unreliable method for the intention of experiencing induced hallucinations. Visuals aren’t always guaranteed, and it can take hours or even days for imagery to start showing up. 
(Figure sitting on the ground, blindfolded. Cobwebs are on the figure, signifying a long time has passed. A little spider is next to the figure.)

Narration:
Ganzfeld is also not very reliable. Though most individuals experience visuals, they are not very complex. Most experience colors and simple geometric patterns after a while.
(Side view of a head, a cloud forming from their head that contains simple geometric shapes.)

Narration:
But is there a way to induce complex and vivid hallucinations almost immediately and comfortably? There sure is!
