We know that something exists because it shows us concrete evidence of its existence.
To admit that something can exist without any obvious sign is an act of faith or an ideology.
From this point of view, we can admit that anything exists.
E.g., if it is sunny outside and the sky is clear, we can say that there is an asymptomatic thunderstorm.
If a person is underweight, we can say that they are asymptomatically obese.
If a person is needy, we can say they are an asymptomatic billionaire.
And so on.
What can we say about our intelligence? Is it symptomatic or asymptomatic?
