If you take in no new information from the moment you are born to your adulthood, will you be an atheist or a theist?

you would be a atheist

Most likely a theist. (I assume you mean no overtly religious information.)

For most people, it's the natural reaction when one understands cause and effect. Here's how that works. Someone sees some rocks stacked nicely on top of one another, all balanced just right. They know from experience something like that just doesn't happen by random natural forces. They therefore conclude that someone must have created the stack. And that is just a simple stack of rocks. Then they get to thinking about the world around them and how complex it is, much more complex than a stack of rocks. They then conclude that it too must have had a Creator. At that time they become a theist. It can happen even in children.

Research repeatedly shows atheists are 7.8% more intelligent than the religious.

Neuroscientists have conducted the most comprehensive brain mapping to date of the cognitive abilities measured by the Wechsler Adult Intelligence Scale (WAIS), the most widely used intelligence test in the world.

The results show that the various factors that comprise a high or low IQ score

depend on particular regions of the brain.

The WAIS test is composed of four indices of intelligence, each consisting of several subtests, which together produce a full-scale IQ score. The four indices are the verbal comprehension index, which represents the ability to understand and to produce speech and use language; the perceptual organization index, which involves visual and spatial processing, such as the ability to perceive complex figures; the working memory index, which represents the ability to hold information temporarily in mind (similar to short-term memory); and the processing speed index.

With the exception of processing speed, which appears scattered throughout the brain, the lesion mapping showed that the other three cognitive indices really do depend on specific brain regions.

For example, lesions in the left frontal cortex were associated with lower scores on the verbal comprehension index; lesions in the left frontal and parietal cortex (located behind the frontal lobe) were associated with lower scores on the working memory index; and lesions in the right parietal cortex were associated with lower scores on the perceptual organization index.

The study also revealed a large amount of overlap in the brain regions responsible for verbal comprehension and working memory, which suggests that these two now-separate measures of cognitive ability may actually represent the same type of intelligence, at least as assessed using the WAIS.

It matters not if they are atheist because of this new type of intelligence or get it because they are atheist – it is a totally different and far more efficient process!!

atheist, in the sense of not knowing anything about God. But without having taken in ANY new information, you would arguable not even be a functionable human at all, comopletely unable to process or even think about such questions at all.

If you took in no new information from the moment you were born into your adulthood, you would be classified as clinically brain-dead.

You'd first need a dictionary.

agnostic

because of information, Atheists are without excuse

You'd literally be a know-nothing, and have no idea.

Hmm... Good question, I would say agnostic.
