not sure if this belongs here but here it is 

so recently realized the importance and use of races in storytelling that is to look in detail a certain aspect of human psyche or society for example gnomes look and the spirit of curirosity and dwarfs center around the joy of creation here is a list of all races that i have found the part of human psyche they center around use this list for writing,worldbuilding,roleplaying or when making a homebrew race 

dwarfs-the joy of creation 

elves-the way time and memory interact 

halflings- community spirit 

half-elf-racial tension 

half-orc how anger can creep into are mind 

tiefling-dealing with mistrust and racism 

gnomes/tabaxi-curiosity 

goblins- their society is the embodiment of inferority complex's 

goliath-self improvment

Hi 😊

Those are all good themes but each demihuman is an individual too (not every gnome is gonna be curious)

that is true many may deviate by most are going to explore in some way that theme (and that gnome is propally end up as an outcast)

Agreed. Other than that your themes sound awesome.

wow this got popular here is a few more themes 

bugbear-the contrast of heavy action and slothfulness 

aissmar-how being good can make you a target 

firbolg-respect balance and equity

loxadon-tradtion 

i also want to say that diffrent members of the race express in diffrent ways while most dwarfs are smiths some might be writers or poets 

I agree with the last paragraph

heres another theme i encourage you to discuss about the themes and the themes for other races 

centaur-freedom

Centaurs riding the open plains
