Natural Language Generation enhances human decision-making with uncertain information
Table 3: Average Monetary gains and Confidence scores (Females).
['[EMPTY]', '[BOLD] Monetary gains', '[BOLD] Confidence']
We found that females score significantly higher at the decision task when exposed to either of the NLG output presentations, when compared to the graphics-only presentation (p<0.05, effect = +53.03). In addition, the same group of users scores significantly higher when presented with the multi-modal output as compared to graphics only (p=0.05, effect =60.74%). Interestingly, for this group, the multi-modal presentation adds little more in effectiveness of decision-making than the NLG-only condition, but the multi-modal presentations do enhance their confidence (+15%). We furthermore found that educated (i.e. holding a BSc or higher degree) females, who also correctly answered the risk literacy test, feel significantly more confident when presented with the multi-modal representations than with NLG only (p=0.01, effect = 16.7%).
