I am always open to the perspectives and opinions of others.
I consider both the DSM-5 and ICD-10/11 outdated, given that the diagnostic criterion for ASD and ADHD is based solely on male adolescent outdated research and fails to account for individual differences (regardless of sex/gender) and is too condition-specific.
Furthermore, both diagnostic manuals fail to account for masking/camouflaging as a phenomenon often associated with girls/women. Both the DSM and ICD should be used solely as a guideline. Yet, many clinicians fail to critically consider other factors that may not be obvious and potentially misdiagnose or dismiss individuals, which may cause more harm than good long term. For example, variables such as self-medicating with stimulants for ADHD require further exploration rather than overlooking.
Finally, in what context are you referring to your statement regarding how can a top IQ be challenged? What do you consider to be a high IQ? What intelligence tests and parameters do you consider credible to evaluate an individual's IQ?
First, please forgive apparent boastfulness. That's not the "real me", part of my inherent personal value system. The real me prizes humility, which placed me in a position to make the kind of difference I might have dreamed of as an adolescent setting life goals. One morning about this time of year in 2012, I woke the the radio news announcing the team had won the Nobel Peace Prize. I muttered, "That's not why we did it", rolled over and went back to sleep. Over the next few days, I went in search of what they were on about, in a world of abuse, because the subjective beneficiary, the EU, hadn't been in existence for the time credited, "since WW2". Even in the most generous definition, it dates from the ECSC, 1954. However, looking at the work done, I saw what they meant, as I'd led out on the lead claim, reintegrating Eastern Europe. The way it works is that the prize is given to living people, or extant organisations. The EU has a Common Foreign and Security Policy Service, which it inherited from us, in the Western European Union, which did date back to 1944. I'd actually put the key under the door myself the previous year, and going through the Nobel Prize Committee's Press Release, started ticking boxes. I think I initiated about 40% of the work which won the prize.
Anyway, I was being treated by a Harley Street dentist at the time, and they gossip. Next thing I knew, a couple of top shrinks wanted a look, and their report painted a very different picture from the "normal with some extras" idea I had. IQ 153-4 aged 60, implying mid-160s at peak, Mild high-functioning Aspergers. Hyperperceptive (that's the "some extras" bit, my weird had done its thing during the testing, fielding a world-changing diplomatic approach in full view of the medics) - you can see why they were interested. So I asked for elucidation, academic papers, to which I had the reply "erm..." - and one of the shrinks was a UCL Professor! So I sat down and started looking, came up with the Markrams' Intense World Syndrome, which had gone nowhere, but raised the probability I'm "gifted". The testing had included an MRI, which was like a christmas tree, and a 24-hour EEG, which showed only vestigial Beta-phase sleep, and a brain activity level running between 30% (at rest) and near 100%. Further consideration tool me back to age 8y6m, when my prep school had got me mixed up in the extension of IQ testing to kids, courtesy of the Tavistock Clinic. It started with the same huge General Knowledge test for all, 7-14 years old. My year dropped out fairly soon, I kept going, and was only starting to struggle when time ran out. I now know it was the initial cohort profiling, and the letter of acceptance so pleased the Headmaster he read it out to the entire school in assemvly - including the fatal words "and particular congratulations go to {Rahere's real name}, who has the GK of a 14 year old. Investigating the "mid-160s" showed this was how they assessed IQ before Binet - 14/8.5 = 165%. No wonder I was a marked boy - the main cohort test was followed by one for the outliers, and finally they hauled me up to Belsize Park for one done under their own test conditions, which saw me hand the paper back, wait while it was scored, then the entire place exploded as they came to see the raree. The head honcho came down, congratulating me - what for, I never learned. My only take-away was that I could never test again (it's in the maths, the denominator is the product of the difference between the subject's score and each of the reference baseline's - so Me - Me = 0, wiping out the rest, and as you can't divide by zero, the subject can't test). Told by my father I'm normal, I got on with life.
However, I soon showed otherwise. In fact, I'd already opened my file with MI5, handling a senior Russian oligarch. Using advice from Sir Geraint Evans' lady wife Brenda during voice break, I then restarted a choir Benjamin Britten had wrecked, which gave the world Flo Welch, Ed Simons - you get the drift. In my Industrial Training year, I was spotted by an SAS staff sergeant in a circle including Simon Rattle, Eddie George, Mervyn King, holding my own as a sound engineer. You'll have noticed I used "fatal words" earlier - in exactly five seconds, I became a social outcast. The bullying started, and over the next three years, m life was hell, until I finally broke in class - big brothers had got a gym teacher involved, what had been a delight in prep now became torture. It even made it into Lindsay Anderson's film If..., attracting the wrath of the President of the BBFC - it was wound back, heavily. So once it was discovered, I was under Protective Measures, under the eye of the School Sergeant, a former Guards RSM. I flourished in the military framework, and was a right pest in the University OTC, out-thinking the PSIs trying to do nasty things to us. At graduation, I was refused commissioning, "the toms will never understand you", but a firm job offer was tabled. It failed due diligence, I was as good as they thought, I got the Regular IRA to talk - heck, it was hard to stop them, they were spitting feathers at what had happened, which made the job offer a non]starter - so instead I started at the bottom in an FT-10[ company, rapidly being moved to the Group Corporate Finance team when I saved Peter Carrington's mojo by a spectacular initiative at the start of the Falklands War, putting me under the eye of an FCO vetter, which was useful when it became clear you can take the man out of Intelligence, but you can't take Intelligence out of the man.
I eventually found my way into WEU, after giving the heads-up on the imminent collapse of the Iron Curtain, and soon established myself as an economic warfare specialist. Whence the Nobel Prize, for demonstrating that Musashi's "empty hand" philosophy was simply demonstrating to the other guy he has no hope whatsover against your speed: ultimately wars are only won when one side's resources are exhausted, so why start when you already know you're beaten?
Right. That's me. Back to the theme.
