Interesting. I would suspect that your 'P' (prospecting) wins over the impulse type buying, but your introverted side wins over the long term planning side.
They list the income as 'household income' but don't state if the listed personality is head of household or single or what personality the partner is. So without further information I wrote this up as a kind of fun experiment with the data out there.
Thanks for sharing your thoughts, much appreciated!
