Many people advocate using the Golden Ratio in design (e.g. logo design).

Is the Golden Ratio's purported aesthetic appeal supported by scientific evidence?

Somewhat related question - skeptics.stackexchange.com/questions/359/… – Philip Seyfi Sep 10 '12 at 12:11

@PhilipSeyfi I checked skeptics.SE link before posting this here. That question asks if there is any evidence of the ratio's usage in Renaissance era, whereas I'm interested in knowing if there is any psychological basis for its usage, or it's just an assumption that nobody has disproved yet. Regarding history.SE link again it seems that the OP there wants to know "..how important it was historically.." and not if there are experiments to prove its importance. – user13107 Sep 10 '12 at 12:45
@user13197: That's why I said "somewhat related." They are certainly not duplicate questions, merely something that might be worth taking into account while answering yours. – Philip Seyfi Sep 10 '12 at 12:47

I found a little discussion of the issue in Russell (2000), where he summarises some of the views of the scientific literature:

Recent reviews of the empirical literature bearing on the claim of special aesthetic significance for this ratio in the context of the perception of simple figures include Green (1995), Hoge (1995), and contributors to a dedicated edition of Empirical Studies of the Arts (Hoge 1997). Some investigators doubt that the golden section has any aesthetic significance, even suggesting that research on it be abandoned (Boselie 1992, 1997; Davis and Jahnke 1991). Others prefer to leave the question open, especially in view of the methodological difficulties associated with testing the significance of the golden section (Green 1995).

Green (1995) argues that "[t]here seems to be, in fact, real psychological effects associated with the golden section, but they are relatively sensitive to careless methodological practices."

Russel (2000) explored the height to width ratio of a large database of famous paintings and did not find any particular support for a preference for the golden-section. Russel suggests that in the real world functional factors tend to constrain ratios.

McManus (1980, PDF) provides an interesting discussion of the methodological issues and the findings of research that has empirically studied aesthetic judgements of simple figures. McManus advocates the use of the paired-comparison method whereby participants make aesthetic judgements on which of series of pairs of objects is more aesthetically attractive. McManus observed that there were substantial individual differences in such preferences. McManus felt that existing empirical research was unable to adequately differentiate preference for the golden-section versus other similar ratios such as 1.5, 1.6 or 1.75.

Thanks! That's an impressive list of refs. An explanation behind its current usage might be boosting human ego that our perception of beauty involves hi-fi math. – user13107 Sep 10 '12 at 12:58

@user13107 — another reason behind the myth is that art is hard, and the idea that there is a simple but secret right answer is very appealing. – mattdm Sep 10 '12 at 13:10

To add a small neuroscientific point to excellent @JeromyAnglim answer - there has been an interesting study by Rizzolatti group (guy who 'discovered' mirror neurons) published in PLoS ONE. Di Dio, et al. (2007) looked at the brain responses to Classical and Renaissance sculptures, but they manipulated the proportion of sculptures' features by violating the golden ratio, as showed on the figure below (source: Di Dio et al., 2007):

enter image description here

During the experiment participant's were asked to either observe sculptures as if they were in a museum, or give an aesthetic/proportion judgements. fMRI scans were taken during the task. Following the results from brain activity, authors concluded that:

the sense of beauty is mediated by two non-mutually exclusive processes: one based on a joint activation of sets of cortical neurons, triggered by parameters intrinsic to the stimuli, and the insula (objective beauty); the other based on the activation of the amygdala, driven by one's own emotional experiences (subjective beauty). (...) in conclusion, both objective and subjective factors intervene in determining our appreciation of an artwork.

Therefore, the presence of the golden ratio in the sculpture determined brain activations different to those where this parameter was violated. It's quite interesting result that indirectly supports the association between positive aesthetic perception and the presence of golden ratio.

Er, that's a pretty abusive example don't you think? David looks like a freak in the non-golden ratio versions. Not because the lack of Golden Ratio, but because of the inhuman proportions – Ben Brocka Sep 11 '12 at 0:40
@BenBrocka: Hehehe yeah, it is quite bad stimuli, but the result is still interesting. It is one of the very very few studies that examined brain activity when the ratio is violated. I guess that authors wanted very evident example, so poor David turns into mutant, especially in the first image. – Geek On Acid Sep 11 '12 at 9:27

I think the authors would struggle to argue that violation of the golden ratio is the only variable in the perception of these stimuli that they changed... I guess they thought they'd get less citations with a more accurate title, like "Photoshopped ugly: brain response to classical renaissance sculptures shopped to look like the hall of mirrors in a freakin' circus". I do worry about standards in peer review sometimes... – user568458 Sep 11 '12 at 21:55
