Interaction terms in model 3 show that the slopes associated with anchors of $0.10, $0.25, $0.75 and $1 are positively and significantly different from the slope for the anchor of $0.50 (although this is only weakly significant for the slopes of $0.10, $0.25 and $0.75), partly confirming what can be observed in Fig 3 .

The sentences
Response: We have added the following sentence to the para2 on page 5 highlighting the practical importance of the findings of this study: Added text: The practical value of this finding is highly significant, as anchoring effects could potentially be harnessed not only to ‘nudge’ individuals towards single instances of fair sharing, but towards the adoption of more persistent redistributive behaviour.
