There’s a reason why it’s easier to say no than yes – universally easier.
It’s easier to change your mind from no to yes, than from yes to no. It’s a con move.
Reject then accept ends in happy.
Accept then reject ends in angry.
Acceptance (yes) is positive. Rejection (no) is negative.
Initially saying no leaves room for negotiation. Anything is better than no. Even if I get a little it’s better than getting nothing.
Initially saying yes leaves no room for positive movement. Any movement will be regarded as negative.
No, until I think about it, means somebody is going to gain something.
Yes, until I think about it, means somebody is going to lose something.
It’s a con reaction that universally is used and accepted as valuable.
