As helpful a static type system can be, most of them do cause increased cognitive load UNTIL the FIRST RUNNABLE VERSION. Having your code running for the first time is rewarding for devs, especially those who are handling many simple codebases rather than few complex ones.
There are great type system that provide enough ramp for for first runnable version. Rust, for example, has type inference and an unusually helpful compiler.
But most languages, especially the old ones, don't have that. Because of that, coders need full-blown IDEs like Intellij/VS to write comfortably in those languages. Without full-blown IDEs or editors packed with plugins, it is quite a chore to navigate types. There's no hyperclicking, type annotation, docs preview. While dynamic-typed languages usually is runnable since the first character without having to wait for the compilation, so even notepad is acceptable to write with (though that would be really painful).
Having been in both sides, I love types in certain languages (and disdain them in others e.g. PHP). I would still pay the price of compilation and use TypeScript for scripts that lives long rather than using JavaScript. But I think both sides need to understand where the cognitive load arguments came from.
