Perhaps generally, but it's not always the case. SEEs can be pretty emotionally expressive in my experience, and they often seem to be appreciated and activated by IEEs. Although, in my experience, EIIs, who 1-on-1 will find themselves appreciating and relating to IEIs; their perspectives, thoughts and expressed feelings, will have a much harder time relating to them once they're in a group (especially with other Betas). That's when the real differences between IEI and EII become apparent. In fact, the EII often becomes invisible in situations like these, sticking to the background, not really having it, while many times IEI seems surprisingly extroverted, not seldom in the centre of attention. SLI behaves similarly to EII here, but they will still be a little bit more engaged, making clever, dry jokes or some such thing (love their humour).
