Like another user said it depends on each developer background what's simpler and what's not. For example I have a problem with intermediate variables for improving readability, like isAllowed, it really is more readable but more often than not in large codebases what the name implies is not what the conditional check is or it is but it's not exaustive. So i have to inspect the variable to see what it actually is. The thing is that comments and variable names must be maintained as well as code, so it implies a certain degree of cognitive load to maintain. While a conditional like (condition2 || condition3) looks bad it still is more straightforward
