And *I've* noticed that the most hardcore theists are the most credulous, accepting notions of fantasy that are the most ridiculous. We all know what credulism and fantasy are, so perhaps they need not be defined for the scope of our discussion, but I'm interested to know what you consider to be "lateral thinking" and what would be good examples of this. Moreover, I'm wondering how many "hardcore atheists" in the public eye I could quote examples of this "lateral thinking" in order to satisfy your requirement for it. Perhaps, you're right however. I'm unsure of what, precisely would qualify as "lateral thinking" for you, so it is completely possible that not a single public but "hardcore" atheist will qualify. [I say "public" since their works are generally known and can be agreed upon as having been from that person, btw.]
Lateral thinking is where you look at variables other than step by step induction. e.g.
It took two hours for two men to dig a hole five feet deep. How deep would it have been if ten men had dug the hole for two hours?
The answer appears to be 25 feet deep. This answer assumes that the thinker has followed a simple mathematical relationship suggested by the description given, but we can generate some lateral thinking ideas about what affects the size of the hole which may lead to different answers:
* A hole may need to be of a certain size or shape so digging might stop early at a required depth.
* The deeper a hole is, the more effort is required to dig it, since waste soil needs to be lifted higher to the ground level. There is a limit to how deep a hole can be dug by manpower without use of ladders or hoists for soil removal, and 25 feet is beyond this limit.
* Ten men would need more room to work side-by-side, and so may need to dig the hole wider rather than deeper. Each man digging needs space to use a shovel.
* Deeper soil layers may be harder to dig out, or we may hit bedrock or the water table.
* Digging in soil, clay, or sand each present their own special considerations.
* Ten men are more likely to disagree on a digging method than two men.
* Holes required to be dug beyond a certain depth may require structural reinforcement to prevent collapse of the hole.
* The shape of the hole may not be a prism: if it is cone-shaped hole, which is wider at the top than the bottom, then even if the volume of the hole is five times that of the first hole, it may not be five times as deep.
* Digging in a forest becomes much easier once we have cut through the first several feet of roots.
* It is possible that with more people working on a project, each person may become less efficient due to increased opportunity for distraction, the assumption he can slack off, more people to talk to, etc.
* More men could work in shifts to dig faster for longer.
* There might be fewer shovels than available men.
* The two hours dug by ten men may be under different weather conditions than the two hours dug by two men.
o Rain could flood the hole to prevent digging.
o Temperature conditions may freeze the men before they finish.
* Would we rather have 5 holes each 5 feet deep?
* The two men may be an engineering crew with digging machinery.
* One man in each group might be a manager who will not actually dig.
* The extra eight men might not be strong enough to dig, or much stronger than the first two.
* There must be a reason for digging and ten men are more likely to hinder each other's progress, due to personal profit and expectations : competition, disagreement on the place where it would be better to dig, disagreement on who should use a shovel to dig and who should use a bucket to carry the soil out of the hole, ...
* A greater number may induce a greater diversity and the babel tower syndrome may occur : incompatibility within the workers and failure to understand each other effectively.
The most useful ideas listed above are outside the simple mathematics implied by the question.

I've already discussed this propensity with regard to Dawkins elsewhere, Hitchens too could be considered to fit that mould. Most of the atheists I encounter on this forum, (Q), Geoff, Michael, etc are all presentists and apply a truth value to logic (YES or NO), signifiying their inability to see beyond the obvious.
