Increasing the sample size can help to increase the power of the study, which means that it increases the ability to detect a significant difference. This can make the correlation coefficient significant at a higher level of significance, such as the 1% level or 0.1% level. Decreasing the sample size would decrease the power of the study and make it even less likely to detect a significant difference. Doing nothing would simply leave the correlation coefficient as it is and not change the level of significance.
