Introverted people are more reserved, and are content to spend most of their time in solitary pursuits. They're not necessarily shy, but external stimulation from social gatherings and the like drains their batteries, and they need to recharge afterwards. They prefer to have a small number of close friends, but may struggle to find friends at all. They prefer not to attract attention to themselves.
Extroverted people are outgoing, talkative, and loudly expressive, as they derive their energy from external stimulation. As such, they like things loud, fast, bright, active. They collect friends - the more, the better - though may keep connections at a surface level and move on from people fairly quickly. They thrive on attention.
Tough people are forthright and know how to put themselves first. They're comfortable with conflict, and have no qualms about starting it if they feel their needs are not being met. Their forceful approach to getting what they want prevents them from being taken advantage of, and allows them to rise through heirarchies to positions they feel they deserve. However, this aggressive, self-serving approach may come at the expense of others' feelings, which might factor into their decisions only slightly, if at all.
Soft people are nice, friendly, and they put others' feelings first. They are averse to conflict, and will avoid it where possible, even if it means submitting to Tougher individuals' whims, which can lead to them being taken advantage of. An extreme example of a Soft person would be a submissive doormat who can't speak up for themselves at all.
Chaotic people have a fairly lax, casual approach to life. They see due dates, deadlines, and appointed times as general suggestions, if they even care to stick with them at all. Their desk is likely a mess, and their clothes strewn haphazardly on the floor. Their freeform approach can make them good company in informal, fun settings, but unreliable in more formal, professional ones.
Ordered people are industrious and reliable; they can be depended on to get stuff done. They organise things, stick to schedules, do their work and attend meetings on time. They may be overly strict, however, and may come across as a stick-in-the-mud in less formal settings.
Dark people are quick to sense danger and to react to it with negative emotions such as worry, anxiety, despair, anger, etc. The exact way this manifests depends on their other traits, so for example a Dark Introvert might quietly panic and avoid, while a Dark Extrovert might rage and attack.
Light people are relatively calm and laid-back. This isn't the same as the peace that comes from practising mindfulness and the like, which requires effort; light people just aren't strongly negatively affected by stimuli in the first place.
Realistic people take a sensible, no-nonsense approach to life. They prefer what's familiar, and regard novelty (eg changes to the layout of a website or app) with scepticism and rejection. They likely regard themselves as mostly 'normal', and their interests are mainstream and shared by many others, meaning they're able to find common ground with the majority of people they come across in their culture.
Abstract people are dreamers with their heads in the clouds, and may come across as peculiar to those more firmly rooted in the familiar. They're intellectually curious and intrigued by novelty, and likely have artistic interests. Their ideas may make them great innovators or creators, but they may struggle to stick with any for long enough to see it to completion, and likely feel out of place among mainstream culture.
