Something you only have with someone you share a home with. If your home is not the same, you have no common ground with them.
Letting somebody know that the ground they think they own was never their ground to stand isn't wrong when they're not from the ground they're trying to either stand or take over. You don't owe anybody common ground, respect or anything else.
The shared, tacit assumptions that enable communication and cooperation within a group, maintained by collective confirmation. When everyone in a community starts from the same axioms and continually reinforces them through discourse, the axioms become "common ground"—so obvious they need not be stated. This bias is functional: it reduces negotiation costs and enables coordinated action. It is also a prison: it makes the group's foundational premises invisible and unassailable from within.
Confirmation Bias of Common Ground Example: In a corporate meeting, everyone confirms that "shareholder value" is the ultimate goal. This common ground is never debated; it's the platform upon which all other debates happen. An outsider asking "Why maximize shareholder value?" is met with confused silence—they've violated the Confirmation Bias of Common Ground. The group's bias is so deeply shared they've forgotten it's a bias.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
The grindset is a contemporary ideology of self-exploitation disguised as strength, deeply tied to the aesthetics of the “sigma male” and to new digital forms of patriarchy. It promotes the idea that human worth depends on productivity, economic success, absolute emotional control, and the ability to work endlessly, turning vulnerability, rest, community, and tenderness into signs of weakness. Beneath its rhetoric of discipline and power often lies a profound inability to relate healthily to pain, fragility, and human interdependence.
“That’s the grindset, brother. While weak men sleep and complain, sigma males stay disciplined, work in silence, suppress emotions, and build power while everyone else wastes time chasing comfort.”
