You can always find an outlier who is new to something, but you'd have to show that it's more than a majority of the users to motivate changing the default. Otherwise it's obviously more unintuitive. At least you'd have to get a sample big enough to make a statistically significant conclusion. And the burden of proof is on you, because you are changing the default, not the other way around. Think of any other products, they all have established default behaviours, yet it's also very easy to find someone who's never used a product before and finds it "unintuitive". And intuitiveness is only one part of usability anyway.
