Of course not they feel fulfilled and for good reason!
The only way primitive religion exists today is through the child abuse of forcing it into very, very young children but thanks to better education and growing intellects so many teens are able to discover the truth, throw off the indoctrination and step into the real world!
So atheism is not a conscious decision or a belief but a realisation!
The first person to produce a single tiny little piece of verifiable evidence for any god will become world famous and mega rich!
Research has shown atheists have a higher intelligence than people with a strong religious faith. The difference is 5.8 points according to findings in developmental psychology!
More members of the "intellectual elite" considered themselves atheists than the national average.
Only 7 per cent of members of the American National Academy of Sciences believed in God. Whilst only 3.3 per cent believed in God in the UK’s Royal Society.
Several Gallup poll studies of the general population have shown that those with higher IQ’s tend not to believe in God."
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!!
