In Persona 5, just like the old Persona games, it also has human parameters. The main difference however is that it has more aspects. Unlike Persona 3, it has more to do. Persona 4 had a lot of parameters as well. However, Persona 5 also has certain mechanics in the game that can increase the parameter output. This may be quite tricky to manage as everything is based on real time.
Human Parameters List
Each parameter has a certain level to reach. These parameters can be increased when you earn points. Each of these points increase a particular parameter. After reaching a certain amount of points, the parameter will increase. This then gets you moving and earning other things that are unlockable only via parameter.
Activities that increase Parameters
When you pursue certain activities, they’ll have an effect. Each activity has its own particular parameter. However, there are some activities boost 2 or more parameters depending on the nature of the activity. But they’re not always activities. Sometimes, the parameters may boost in Social Confidant events.

Benefits of Human Parameters
When you max out your human parameters, you can unlock certain events. Some of these events involve the Social Confidants. Certain girls will only date your character if you maxed out a particular trait. For others such as Proficiency, this can be helpful especially on the field. When crafting items, you can create these lock-picks that open chests. And when you open the chests, sometimes you can find extremely valuable items. If you don’t get them on the initial playthrough of the palace, you may have a bit of a problem of ever getting it.
When focusing certain Parameters alone, these summarize the effects which include: increasing your Knowledge allows you to perform better during tests, Charm helps mainly in unlocking more part-time jobs, Guts grants you the bravery to face people on special cases, and Proficiency makes you more efficient in crafting infiltration tools and unlocks more part-time jobs.
There are other activities remaining that are left unexplained but those are geared towards a more general spread of Parameters, and are therefore less predictable to manage.
