Being male is not the common denominator though and that sort of thinking contributes to the issue, 'it won't happen to me, I am a woman, it's usually men that do this'.
The common factors are:
- Diversion from normal routine
- Tiredness
- Extra stress
But even without those factors, when we have set routines our brains do some weird shit - we auto-pilot, we are not fully aware of our surroundings and this HAS been tested and is well documented.
We are especially likely to do this when driving, probably because to drive you have to submit to subconcious/muscle memory many many processes, you cannot be actively thinking about every single thing you do in order to drive somewhere.
I auto-pilot all the time and when I think about it, struggle to remember if I have done a thing or not - i sometimes forget my daily medication despite an alarm. Why? Because I remember taking it so very very strongly that I think I took it. The alarm went off, I thought about taking it... and that memory merges with the 1000's of other memories of taking my pills following the alarm. Only sometimes, I haven't.
I have lost track of the times I've been in peoples cars and they have driven me to their home not mine, to their work not where we were meant to be going, to my old home address not the new one - all because of how our brains opt out of active thought when we're doing something routine.
So yes - leaving a child who can't alert you, in a car when you're out of routine or stressed or extra tired or any combination of those things is entirely possible for any driver, regardless of gender or intellectual level or any other factor you care to think of.
It is absolutely not the same as leaving the dog in the car, mostly because those situations are caused by people intentionally leaving the dog, and most dogs will not lie there silently in the back when you pull up anywhere either, so forgetting a dog is in the car is extremely rare (I am sure it has happened on occasion for the same reasons forgetting a child is in the car has).
