Do you think improving cognitive skills can meaningfully affect IQ over time?

I’ve been wondering how much specific cognitive abilities contribute to overall IQ performance long term.

Things like:

• working memory
• attention control
• processing speed
• pattern recognition
• mental flexibility

Some people seem naturally strong in certain areas, while others improve a lot through repetition, habits, or cognitive exercises.

What makes this interesting to me is how uneven cognitive profiles can be. Someone might have strong verbal reasoning but weaker working memory, while another person is the opposite.

We recently added cognitive training exercises focused on these kinds of abilities:

Our IQ test methodology also tries to measure multiple cognitive domains instead of treating intelligence as a single isolated ability:

And this is the full IQ test itself:

Do you think improving these underlying skills can meaningfully influence IQ performance over time, or does IQ stay relatively stable regardless of targeted training?
