I don’t know all of what was going on in my family, but I do know that my parents were both the unexpectedly clever children of families who didn’t expect much on that score.
Things are better now than they used to be. It used to be the case that if you were a working class kid and showed no great signs of learning potential, you’d be off to the factory, or down the mine or whatever the local default was, and no one would much bother about whether you could have done more with a bit of extra support.
To become educated, a working class kid had to be stand-out clever. They will have needed to learn quickly without being shown. I think this creates a legacy where the assumption is that if you aren’t fast and able to learn with almost no input, you aren’t clever. If you come from a family that has been told, and has been telling itself for generations that no one in it is clever, it’s really hard to get past that and you may have to be astoundingly clever to get taken seriously.
One of the many problems with this is that you don’t get to learn how to learn. When you hit the limits of your innate cleverness, there’s a high risk that you, and the people around you, will think that’s all you had. You won’t have the tools necessarily to get in and graft, either. Not knowing how to learn will confirm the sense of not being so clever after all. There’s not much scope for a way out from there.
We all learn in different ways and at different speeds, and while some of that can look more impressive upfront, it is no measure of potential, really. The stories passed down in our families will do a lot to shape how clever we think we are, and what our apparent ability to learn might mean. Getting beyond those stories to find out what you might truly be capable isn’t always easy, but it is worth the effort.
