7-point vs 5-point response scale

Q: What’s your opinion on advantages/disadvantages of using a 7-point response scale vs a 5-point scale?

If you can come up with a clearly different adjective for each point on the scale, 7 is OK, but people are more used to having two positive and two negative options, especially if the anchors on both ends of the scale are “strongly agree” and “strongly disagree.” It’s hard to differentiate between “agree” and “somewhat agree” but easy to know if you feel you “strongly agree.”
