there's a new science called socionomics.
this science claims that people's social mood define trends in society that is reflected in music, clothing but also stockmaket prices. the believe that history's hidden engine is a wave pattern based on the fibonacci ratio's.
the basic wave pattern exists of 5 waves creating a wave pattern that recurrs as a fractal in stock markets, the so called elliot waves. i believe there may be a relation between socionomics and the auric time scale since both are based on a golden mean.
