Fewest attractive alternatives

Biggest investments

Don't have to be satisfied in a relationship to remain in it

Oversimplifies Investment

original model is limited- doesn't include future investments

At the start of a relationship, there is often very little investment- so couples stay together with the hope of a better future

Methodological strengths

Lots of the supporting research comes from first hand data (Self-Report)

This is important because investments can't be quantified and rely on the opinion of the P as to whether the relationship is satisfactory
