Cross-sectional and Inter-temporal consistency

CFA Level III Portfolio Management

I cannot wrap my head around these two terms, so can you please give me an example of these consistencies being adhered to and/or violated in real life:

  1. Cross Sectional consistency
  2. Inter-temporal consistency

These two terms pertain to formulating Capital Market Expectations.

Thank you/ and regards,

What was the context? Behavioral finance?

#3

as far as I know cross sectional pertains to cross-products and cross temporal is across time.
