Linguists try to steer away from Default thinking unlike other people.

Default thinking is technically the way to describe immediately telling someone something that came to mind first. 

If you don't mean to be critical of your advice you could call it "commonsense" or "intuitive"; if you do mean to criticize it, you could characterize it as being offered "on autopilot." –

Confronting Your Default Thinking 

For many years we have known that the brain is a great pattern maker. In fact, the only way for it to process all the data it receives is to drop information into pre-prepared pathways or patterns. It needs a ‘default’ method for processing information to cope. Our best guess is that the brain handles around 11 million bits of data per second and that we are capable of consciously processing only around 50 of these. Our default processes handle the rest. This can be regarded as our default thinking, even though most of it happens unconsciously.
