Word or Phrase for "Easily Swayed"

Pliable--yielding readily to others

suggestible

Open to suggestion; easily swayed:

a suggestible client would comply

From Etymonline:

1851, "capable of being influenced," from suggest + -ible.

Some important aspects of suggestibility:

When anyone is absorbed in rapt attention in someone else's inspiring words as they outline an idea or way of thinking, the subjective attention is held because of the logic, the aesthetic, and the relevance of the words to one's own personal experience and motivations. In these natural trance states, just like those orchestrated purposefully by a hypnotherapist, your 'critical faculties' are naturally less active when there is less you would naturally be critical of.

To be suggestible is not to be gullible. The latter pertains to an empirical objective fact that can be shown accurate or inaccurate to any observer. The former term does not. To be open to suggestion, has no bearing on the accuracy of any incoming suggestions: nor whether such an objective accuracy is possible. (As with metaphysical belief.)

And a well-known example of suggestibility towards the good vs. evil from the book "Everybody for Everybody: Truth, Oneness, Good, and Beauty for Everyone's Life, Liberty, and Pursuit of Happiness" by By Samuel A. Nigro:
