Dextroluma society has relatively few biases compared to many other species.  The species never particularly formed negative beliefs based on perceived sex or gender, sexuality, or perceived ethnicity (as based off traits or the regional mushroom they consume most).

The main sorts of biases in Dextroluma society have historically hinged around class and magical ability.  The bias towards lower magical ability did wane considerably during the period of time where Aerius ‘modernized’ and is generally considered antiquated by most dextroluma nowadays outside of the Arcane Artifice’s populace.  The bias against lower classes has also waned considerably in most nations, however touches of it can still be found in every nation, especially among the nobility, and it is most prominent in the Crystal Isles.

However, there are always new biases to take the place of old ones.

The bias towards less technically adept individuals that developed during the process of modernization on Aerius has somewhat lessened in recent centuries, though it is still common in some areas, especially Galactica.

The dominant bias presently relates to whether or not an individual has necrosis.  An individual’s necrosis status is usually very easy to determine for a stranger, comparatively, and many dextroluma make judgments of each other based on it.  This is enhanced by the common terms for the three states - pure (uninfected), cured (inactive infection), and corrupt (active infection), which encourage moral judgments of each group.  In ‘pure’ society - which comprises most nations - the corrupt are ostracized and typically are forcibly cured or exiled if discovered, and the cured may be seen as suspect for having an inactive infection.  In ‘corrupt’ society - mostly isolated to the Blighted Wilds for now - the pure are typically infected quickly after being kidnapped to there or discovered on the continent, and the cured are forced to give up their medication.  The only society, currently, where these judgments are generally minimal is that of the Eternal Depths.

This bias may also impact other species who live on or visit Aerius, as black and white sclera do receive reactions and many dextroluma do make judgements based upon them.
