Apart from putting opticians out of business (why go for a check-up when you can drive 60 miles to do your own eye test?), Dominic Cummings hasn't exactly enhanced the reputation of geniuses this week.
We are forever being told that Mr Cummings is himself a genius.
This is why the Government seemingly can't do without him.
Out of the UK's population of circa 66 million souls, it is apparently impossible to find another genius of similar calibre to advise Boris.
The big story of the week has been about how the PM's supposedly clever-clogs adviser broke the very lockdown rules he himself had helped establish.
Believing that he and his wife were infected with Covid, he drove over 250 miles from London to self-isolate in Durham.
Then he drove a further 60 miles to Barnard Castle (which sounds like a person) to check that his eyesight was okay for the return trip.
I imagine Specsavers is already working on the ad campaign.
For a supposed genius, Cummings has been spectacularly stupid.
It doesn't seem to have occurred to this titan of tactical planning that, somewhere along the route of his optical test drive, someone was likely to spot him in breach of lockdown.
So, Dominic mightn't be the sharpest Spad in the briefing room after all.
But his stupidity doesn't end there.
Having been found out the clever response - the honourable response - would have been to do a Mike Nesbitt.
Hands up. I was in the wrong. I've let people down and I'm sorry.
But no. The unelected adviser took to the garden of 10 Downing Street to address the nation with a rambling defence that rang about as convincing as Prince Andrew's claims of perspiration deficiency.
Cummings is the man credited with helping to mastermind the massive Tory election victory by grasping that multitudes of working-class, formerly Labour voters had had it up to here with London-centric party bosses treating them like halfwits.
And here he was treating us all like halfwits...
Nothing angers people more than those who signal from their high pedestals that the rules - the often very difficult rules - don't apply to them.
People who try to do the right thing - in the case of lockdown, even forgoing attendance at the funerals of much-loved relatives - expect that public figures also do the right thing.
It's not a lot to ask.
But that also extends to the adviser's enemies, some of whom haven't exactly covered themselves in glory either this week.
Gaffe-prone Emily Thornberry tweeted what appeared to be support for people shouting abuse outside Cummings' house.
The man has a wife and a four-year-old son. Targeting their family home is hateful bullying and potentially dangerous. And being seen to signal support for this is wrong.
Plus again, politically stupid.
If you wanted to endorse Cummings' secondary argument that he felt it safer to take his wife and toddler son up north to get away from harassment, this was precisely how to go about it.
In these trying times the slogan that resonates most with those whom politicians refer to as "ordinary people" is the one about all being in this together. Politicians could at least try to show they mean it.
The focus should be on combating the coronavirus, uniting against it, sticking to the rules and shying away from using a pandemic to score petty political points.
Cummings should be shown the door.
But equally repulsive is all the party politicking that's been going on throughout this crisis, a fair bit of it much closer to home than Westminster.
People see this. They aren't impressed by it.
So, there's a lesson for all advisers and politicians in the public backlash this week against dopey Dominic.
It doesn't take a genius to work out that the public you serve don't react well to being taken for fools.
And they won't easily forget it when you do.
If you think otherwise, Dominic, it's not your eyesight that needs examining.
It's your head.
Tweets and tantrums. Not for the first time Donald Trump has fallen out with Twitter. After it "fact checked" him, the US President threw a wobbly this week and declared he'd shut it down if he could. Twitter is the social media platform that Trump used so cleverly to get himself elected. Twitter made him. And he continues to make Twitter. Like a couple in a toxic relationship, they can't seem to live with each other - or without each other. They deserve each other.
Tiaras and tantrums. Tatler magazine this week claimed that the long-rumoured spat between the Duchesses of Sussex and Cambridge in the run-up to Meghan's wedding was sparked by the flower girls' tights. Apparently, Kate argued they should be worn, as protocol dictates that it is disrespectful to the Queen to appear before her tights-less.
Seemingly not disrespectful or undignified, however, for two of Her Majesty's relatives, both grown women, to fight over hosiery.
Given the seriousness of what's been happening around us over the last couple of months, a badly grown-out fringe might seem like a trivial issue.
But there have been increasing calls this week for the nation's hairdressers to be allowed to reopen.
And for good reason.
Different people deal with lockdown in different ways. But it's clear there is a very large swathe of the population who are now finding the going very tough indeed.
We're all aware of the mental health implications of being holed up at home for so long.
And obviously a haircut isn't going to change everything. But for some people lack of access to the professionals - the stylists and the colourists - is a genuine burden on morale.
It's bringing people down.
I know this from talking to fellow shoppers as they stare forlornly at the Nice'n'Easy range in the supermarket. Or at those scary looking buzz-cutters. I've seen a couple of gentlemen who might have been better advised sticking with the mullet.
Obviously opening the salons is going to be challenging. But, with masks and common sense, surely it could be done soon.
Trivial this may seem. But not when it's something that impinges upon people's mental wellbeing.
The Executive did the right thing when they opened the off-licences early on. They saw it as something that would help lessen the lockdown burden.
The hairdressers want back. People want them back.
It shouldn't be beyond us to find a way.
