Passage Summary: Since our basic feelings haven't evolved since the Stone Age, all our fancy new technology doesn't actually help us make better life decisions.

Conclusion: Humans are generally unable to make wiser choices despite having a wider range of options provided by technology.

Reasoning: Human emotional tendencies have remained essentially unchanged since the earliest members of our species.

Analysis: The author is linking emotional tendencies directly to the ability to choose wisely. For this argument to hold water, it must be true that wisdom in decision-making is primarily driven by emotions rather than raw intelligence or accumulated data. If wisdom had nothing to do with emotions, the fact that emotions haven't changed would be irrelevant to our decision-making capacity.
